Dear Vikash,
This requirement you can achieve by maintain the production version in the SFG material MRP4 View
if you have two BOM's for the same material then we will create alternate BOM and assign these two BOM's with two different production versions
then while creating production order system will give a popup for selecting the desired BOM
please check with the name of Production version you will get lot of threads
Regards,
Venkatesh..
