Validity Calculation for BOM Header and Items

This feature helps you to minimize the time consumed during BOM explosion. You can avoid runtime validity calculation and instead run the report CS_BOM_VALID_TO_CALC and BAdI implementations Implementation: Calculate Validity for BOM Header and Implementation: Calculate Validity for BOM Item. This new validity calculation approach will persist the data in the relevant tables while creating or changing BOMs.

The validity calculation supports the below mentioned scenarios:

Changes without release key
In this scenario the fields VALID_TO and ECN_TO in the BOM header table STKO and the BOM item details table STPO are updated with reference to the corresponding change numbers.
Changes with planning as release key
In this scenario the fields VALID_TO_RKEY and ECN_TO_RKEY in the BOM header table STKO and the BOM item details table STPO are updated with reference to the corresponding change numbers. These change numbers are primarily released for planning scenario.

Effects on Customizing

To enable or disable this product feature you have to carry out the Customizing for Determine Explosion Mode under Production Basic Data Bill of Material Control Data for Bills of Material . When the product feature is enabled for the first time, the report CS_BOM_VALID_TO_CALC needs to be run for the already existing data to be updated with the corresponding entries.
The BAdI implementations available in Customizing under Production Basic Data Bill of Material Control Data for Bills of Material Business Add-Ins (BAdIs) help in the insertion or updation of the corresponding entries in the STPO or STKO table when BOM data is created or modified.
