Field help (WST1)

The principal work center corresponds to the production resource on which the routing operation will be performed. It can be of machine, labor or sub-contracting type.
The scheduling of the operations looks at the availability of this work center. It is possible to specify a number of operators in the "Number of work centers" field. It is not possible to allocate to one operation more resources than there are at work center level.
If the work center has been selected with a "sub-contracting" type, the sub-contracting code for the second screen is set to "structural": in other words, the operation is systematically sub-contracted. The sub-contracting operations are managed with a lead-time described in the sub-contracting product record. The operation times are used to manage the equivalent of the load in hours, sent to the sub-contractor for information purposes.
To manage a temporary (or occasional) sub-contracting operation, it is necessary to enter the internal work center in the principal work center and enter the sub-contracting work center in the second screen with a "temporary" sub-contracting code. During the creation of a work order, scheduling is carried out in priority on the internal work center and it is possible to replace it with the sub-contracting work center if the scheduler finally wishes to sub-contract the operation.
