Understanding the Bill of Material Update

For engineering change orders (ECOs) with attached parts lists, you can process the ECO parts list and related items list to update the Bill of Material Master File table (F3002) with the requested changes.

The Engineering Change Population program (R30510):

• Processes ECOs.

• Updates the bills of material for the items on the ECO.

• Creates a report in proof or final mode that describes the requested changes.

• Updates ECO-related information in the Item Branch File table (F4102).

• Updates the Item Master table (F4101) for item flash messages that are based on other outstanding ECOs.

• Validates the ECO for full approval before accepting the requested changes.

• Updates the effectivity dates.

• Updates the drawing revision level.

• Copies substitute items from the old component to the new component.

• Updates the parent or component revision level.

  Important: It is recommended that you first run this program in proof mode. In proof mode, the report lists all of the requested changes without actually changing any records. Review the report and then run the program in final mode to update records. After you run this program and update table F3002, you cannot change the parts list and run the program again.

The Engineering Change Population program updates only the bill of material. You must update the routing instruction to include the same item revision level as the bill of material if you want to synchronize them.
