| To set up and use unit effectivity in Engineering Data Management you must use the Unit Effectivity module in Common. To set up data, refer to To set up unit effectivity. To use unit effectivity when engineering an item, carry out the following steps: Define the engineering bill of material (EBOM) in the Engineering BOM (tiedm1110m000) session. To link exceptions to a BOM line, select the BOM line and click Exceptions from the appropriate menu. The Exceptions (tcuef0105m000) session is started. If the end item is already defined, you can use effectivity units of the end item. Otherwise, use effectivity units of engineering items. The purpose of exceptions in an EBOM is to engineer a generic design. This means that when the design is finished, all exceptions must be copied to the PBOM. Use the Copy Engineering BOM session to copy the EBOM and its linked exceptions to the PBOM. During the copy process, ERP LN provides the user with the possibility to replace the engineering item in the item – effectivity series with a general end item. To do so, ERP LN starts the Relink Item - Effectivity Series (tcuef0201m000) session. At a certain point of time, a general end item must be defined. This is the item that is used on the sales order line. For reasons of clearness, you must link the item – effectivity series that is still linked to the engineering item to the end item. Use the Relink Item - Effectivity Series (tcuef0201m000) session to relink the effectivity series from the engineering item to the end item. You can start this session from the appropriate menu in the Items - Effectivity Series (tcuef0101m000) session. Finalizing Engineering Data If you copy an E-BOM to a PBOM by using the Finalize Engineering Data (tiedm3240m000) session, ERP LN proceeds as follows. If the Unit Effective Supply check box in the Items - General (tcibd0501m000) session is selected for the end item, ERP LN does not copy the effectivity statements.
