You can create a LSMW for creating the production versions of a material.
Do a recording for T code C223.And you do a mass upload for this.
So if you need to create only for few materials use MM02 – Change material ,select
MRP4 view and click on production version icon ,enter the necessary details or
else use directly C223 for creating Production versions.
In case of any clarification,please revert back.
Thanks & Regards
