hi there,
theoretically, the procedure to create schedule line is creating customer-material info record via T-code VD51 firstly before creating the schedule line in T-code VA31.
However, we find that it is ok to create schedule line even though no action taken in VD51.
It seems no impact for the following action.
Does someone know:
What is the effect to create customer-material info record?
Should we always create customer-material info record at first?
Or only do it when warning message pops up in VA31/32?
