Common data > BOMs > Replacement > Components 

Use this function to change (or replace) a component in one or a range of bills of materials with a different component.

You can set the validity start date for the replacement component as required. The default is today's date.

The new component is given the same sequence number in the bill of materials (BOM) as the component being replaced. If the component already exists at the same sequence number the sequence number is incremented.

If the quantity of the replacement component is different you can apply a factor to update the BOM to ensure an accurate substitution takes place. The component 'Where used' flag is updated accordingly.

 This function does not 'delete' the original component, it simply marks it as 'not valid' by setting the validity end date to the validity start date for the replacement component minus 1 day (n-1).

 The BOM displays components that are valid on a specific date. The new component, therefore, is only displayed in the BOM once it becomes valid (fields Reference date (DATREF)/Valid from (BOMSTRDAT)).

Component selection

Type in, or select the code of the component to be replaced and the code of the new (replacement) component.

If the quantity or unit of the replacement component is different from the current component, type in the factor to update the bill of materials (BOM) with.

Leave the default validity start date for the replacement component or select a different date which is later than today. This will be used as the validity start date for the replacement component. 

Then select the types of BOMs (commercial, production, subcontract) to be included in the run.

Start/end ranges

A number of ranges are displayed.

  • To replace the component in all applicable BOMs at all levels of the BOM, leave all the fields as the default values or blank.
  • To replace the component in selected BOMs, type in the required ranges. Leave the first field blank to include the lowest value or the second field blank to include the highest value.

You can optionally select the BOMs by applying a calculation formula.

A log file displays the results of the run. Where appropriate it includes information which should be noted or acted upon.

 BOM codes that you are not authorized to change are excluded from the run.
