Hi,
You can create a different BOM with the new component and the corresponding production version using the new BOM. The production version can be determined according to the validity period. So in case you have 2 alternative BOMs, you will need 2 production versions: e.g.: 0001 and 0002.
PV: 0001 --> Alternative BOM 1 --> From 01.01.2010 to 30.11.2014
PV: 0002 --> Alternative BOM 2 --> From 01.12.2014 to 31.12.9999
Then when you execute the costing run, you can select the production version or you can enter the date in which the production data should be determined.. and then the PV will be automatically selected. E.g: if you run CK11N and say that the date to be considered for the production data is 01.01.2015, then CK11N will determined PV 0002.
Kind Regards,
