Fields
The following fields are present on this tab :
Start - end range
| Filter for results within a range of routing codes. Multiple routings can be defined for a single product. Each routing code can be assigned specific management features. These include restriction of the routing to a specific site and to specific areas of functionality (for use in a manufacturing environment, for costing or for capacity planning). For a single routing code, enter the same sequence number in the from/start Code and to/end Code fields. |
| Filter for results within a range of routings. For a single route, enter the same routing code in the from/start Routing and to/end Routing fields. |
| Filter for results within a range of operation sequence numbers. For a single operation sequence number, enter the same sequence number in the from/start Operation and to/end Operation fields. |
| Filter for results within a range of planned work centers. For a single work center, enter the same work center code in the from/start Work center and to/end Work center fields. The planned work center is attached to a work center group. It corresponds to a production resource on which a routing operation is to be carried out. |
| Filter for results within a range of 'labor' work centers. For a single work center, enter the same work center code in the from/start Labor center (Subcontract work center) and to/end Labor center fields. The work center site of a 'labor' work center must match the site for the routing code, if defined. Scheduling is not carried out for labor work centers as they are considered secondary and 'always available' (or available at the same time as the main work center). Their load is managed for information purposes only using the coefficients defined for the main work center. If the main work center is of type 'subcontracting' there is no associated secondary work center. |
| Use this field to filter the routings according to the selected operation types (normal operations, subcontract operations or exceptional subcontract operations). For a single type of operation, enter the same type in the from/start Subcontract type and to/end Subcontract type fields. The subcontract type defines if an operation is carried out internally or if it is sent to an external (subcontract) supplier. It can be set to one of the following values:
|
| Filter for results within a range of subcontract work centers. For a single work center, enter the same work center code in the from/start Subcontract work C (Subcontract work center) and to/end Subcontract work C fields. A subcontract work center can be used for the following:
A subcontract work center has the work center type set to 'Subcontracting'. Routing operations are validated to ensure the work center site of a 'subcontract' work center matches the site for the routing code, if defined. |
| Filter for results within a range of services carried out by subcontractors. For a single service, enter the same product code in the from/start Subcontract prod (product) and to/end Subcontract prod fields. |
| Enter, select or build an Enterprise Management filter calculation expression using the formula editor.

Fields
The following fields are present on this tab :
Modification
| Use this field to identify the production resource that is to be used for the selected operations. This work center replaces the main (principal) work center for the operations. Type in, or select from the Work Centers table the code of the resource to be used for the operations. It can be a machine, labor or subcontract work center. If you define a work center of type 'subcontracting', the Subcontract code (field SCOCOD) is set to 'Structural' and the operation is automatically subcontracted. The subcontract operations are managed using the lead time defined in the subcontract product record. Subcontract operation times are not used by the scheduling. To generate a temporary (or ad hoc) subcontract operation enter an internal work center as the main work center and the subcontract work center using a temporary subcontracting code. During the creation of a work order scheduling is carried out by priority on the main (workshop) work center. You can replace this work center with the subcontract work center if the operation is subsequently subcontracted. |

Fields
The following fields are present on this tab :
Block number 1
| The site at which the selected routings will be updated. |
| This routing code describes the process involved in manufacturing (producing) or processing a product. That is, the sequence of operations and tools that are involved in producing or processing a particular product. The routing code matches the product code. The product code can be a manufactured product (a bill of materials), or a generic reference to a parent routing which is linked to several products. |
| Multiple routings can be defined for a single product. Each routing code can be assigned specific management features. These include restriction of the routing to a specific site and to specific areas of functionality (for use in a manufacturing environment, for costing or for capacity planning). |
| This field displays the sequence number of this operation. |
| This field indicates if this operation has been amended. The value displayed concurs with the number of times this operation has been amended. The operation with the highest index number is the new operation. |
| This field displays the start date of this operation's validity period. |
| This field displays the final date of this operation's validity period. |
| This field identifies the standard operation used to create this operation. Standard operations are simply 'template' operations that provide default information to be assembled into routings for producing or processing a particular product.
|
| Use this field to identify the production resource that is to be used for the selected operations. This work center replaces the main (principal) work center for the operations. Type in, or select from the Work Centers table the code of the resource to be used for the operations. It can be a machine, labor or subcontract work center. If you define a work center of type 'subcontracting', the Subcontract code (field SCOCOD) is set to 'Structural' and the operation is automatically subcontracted. The subcontract operations are managed using the lead time defined in the subcontract product record. Subcontract operation times are not used by the scheduling. To generate a temporary (or ad hoc) subcontract operation enter an internal work center as the main work center and the subcontract work center using a temporary subcontracting code. During the creation of a work order scheduling is carried out by priority on the main (workshop) work center. You can replace this work center with the subcontract work center if the operation is subsequently subcontracted. |
| This field identifies the type of operation that is performed on the selected work center. This might be a machine, labor or a subcontracted operation. Work centers of type Subcontracting are managed externally by subcontract suppliers. |
| This field identifies the group of work centers to which this work center belongs. Work center groups are used to review workloads. |
| This field displays the description defined for the routing operation. |
| Use this field to assign a 'labor' work center to the selected operations. The work center site must match the site for the routing code, if defined. Type in, or select from the Work Centers table the code of the labor resource to be used for the operations. This work center replaces the existing or assigns a new labor work center to the operations. Scheduling is not carried out for labor work centers as they are considered secondary and 'always available' (or available at the same time as the main work center). Their load is managed for information purposes only using the coefficients defined for the main work center.
|
| This field identifies the group of work centers to which this work center belongs. Work center groups are used to review workloads. |
| This field displays the actual time it takes to prepare this work center. This time forms part of the work center load. It is expressed in the time unit specified in the routing header or in the time defined for the standard operation, if a standard operation has been applied for this operation. |
| This field displays the unit of time in which this operation is measured. |
| The operation time type conditions the production time entry.
|
| Depending on the resource being used, the number of decimals of the operation time can be insufficient to express the production time. |
| The basis quantity entry depends on the management unit. |
| The operation time is the time necessary to manufacture the product described in the routing. The operating time unit can be:
|
| The rate is a number of units produced by minute or by hour according to the time unit specified in the routing header (for an operation), or in the standard operation itself. |
| This field displays the number for this particular production resource that are required for this operation. For example, '3' if three people are needed to operate this (labor) work center. |
|   |
| Efficiency is a way to measure compliance to the preset standards. It can be calculated over a given period by work center: Standard hours calculated for a given production divided by the actual hours worked. Two efficiency rates are managed depending on the following:
If both factors are entered, they add up. The WSTEFFINH - Work center efficiency history parameter (GPA chapter, MIS group) is used to specify whether the efficiency defined at work center level should be used on the routing operation.
|
| This percentage is used to balance the quantities on the production operations based on the released quantity. It is possible to introduce a shrinkage percentage on the work center, which is used to weight the planned runtimes for an operation using this work center by a loss or gain on the quantity produced for the work center. |
| This is the planned setting time to obtain the setting time allocated to the labor work center linked to the main work center. This coefficient applied to the planned setting time to obtain the setting time allocated to the labor work center linked to the main work center. |
| This is the coefficient applied to the planned operation time. It is used to obtain the operation time for the labor work center linked to the principal work center. This field is only available for entry if the labor work center is defined. Operation times are subdivided as follows: Proportional times are expressed for the production of an operation unit (and not in the stock unit of the finished product using the routing). |
| Preparation time is 'waiting time' set at the start of an operation.
Although preparation time is waiting time it can be used for the time it takes to prepare for an operation on a work center. This might be time for settling liquids or cleaning a machine. For this type of scenario, that is when preparation time is used for setting time at the start of an operation, the resource must be available. When scheduling preparation time the calendar for the defined resource is applied. This means that if, for example, a work center (machine or labor) runs from 08:00-12:00 and 13:00-17:00 with a break for one hour between 12:00-13:00, preparation time will be interrupted by the one hour break. If the operation requires an 'emergency release', a reduction coefficient can be assigned that makes it possible to completely remove any preparation time. |
| Waiting time is 'delay time' that occurs after an operation. It is non-productive time such as drying time or cooling time that occurs after a process has been completed on a machine and until the machine can next be used.
If machine time is required for an operation during the allowed waiting time you should add a new operation to this routing. A machine might be required for example, for drying or cooling components at a work center. The additional operation must be for the appropriate resource type, such as 'cooler'. When scheduling time for these resources if, for example, a work center (machine or labor) runs from 08:00-12:00 and 13:00-17:00 with a break for one hour between 12:00-13:00:
|
| Post operation, or post run time is a 'deadline' that occurs after waiting time. It is non-productive time, typically 'transfer time', or a transition period from one work center to the next work center that occurs after a process has been completed on a machine and until the machine can next be used.
If operator time is required for an operation during the allowed post run time you should add a new operation to this routing. An operator might be required for example, for the transportation or carriage, or the transition between two work centers. The additional operation must be for the appropriate resource type, such as 'carrier'. When scheduling time for these resources if, for example, a work center (machine or labor) runs from 08:00-12:00 and 13:00-17:00 with a break for one hour between 12:00-13:00:
If the operation requires an 'emergency release', a reduction coefficient can be assigned that makes it possible to completely remove any post run time.
|
| Work order operation quantities are expressed in the operation unit. Use this operation unit to express operating time in a different unit to that of the product being produced by the routing. For example, a product managed by unit is subject to three different operations, none of which produce intermediate stock:
There is no need to create semi-finished products for each production phase. The operation unit is associated with a conversion coefficient for the stock unit of the product being produced by the routing and the operation unit. |
| The Stock unit-Operation unit conversion coefficient is used to convert the released quantity of finished product into the quantity of the operation according to its unit. |
| The subcontract type defines if an operation is carried out internally or if it is sent to an external (subcontract) supplier. It can be set to one of the following values:
|
| Use this field to assign a subcontract work center to the selected operations. The work center site must match the site for the routing code, if defined. Type in, or select from the Work Centers table the code of the subcontract resource to be used for the operations. This work center replaces the existing or assigns a new subcontract work center to the operations. |
| This field identifies the group of work centers to which this subcontracted work center belongs. Work center groups are used to review workloads. |
| Use this field to identify the service to be carried out by the subcontractor to execute the selected operations. The product category must be of type 'Service'. |
| Use this field to identify the supplier of the subcontracted service. Type in, or select a supplier code from the BP Suppliers table. |
| Use this field to select the address for the supplier assigned to the subcontracted work center, if multiple addresses have been defined for the selected supplier. |
| Use this field to apply a generic price to a subcontract service. This price will be applied (by operation unit) throughout the order process. |

In addition to the generic error messages, the following messages can appear during the entry :
The range you have selected is invalid.
All work centers are linked to a specific site. The site defined for the selected work center must be identical to the selected Production site (field MFGFCY).
These messages are displayed if the selected work center is defined as the wrong type. A labor work center must be defined as type 'labor'; a subcontract work center must be defined as type 'subcontracting'.
This message is displayed if a modification has been requested for a subcontract work center and the subcontract product is missing.
Amendments to the operations in a versioned routing are tightly controlled to minimize the impact on work orders. The selected operation is in one or more version-managed routings. The list of routings displayed will not include version-managed routings as these are excluded from the replacement process.
This message means that for the defined operation there is already a replacement operation in the routing. The initial and replacement operations have the same operation number, but they have been given different indices to distinguish them.
This is an information message. Operations are modified when the modification run is confirmed.
This is an information message. Replacement operations are created when the modification run is confirmed.
