What determines the Requirement Type?
Would appreaciate if anyone can tell what determines the Requirement Type (ReqTy) of the Sales Order.
Two sales order are created using the same material:
(Material used is of Strategy Group 20 : Make-to-order production)
Sales Order #1: The ReqTy is KSL-Sale frm stck w/o ind.req.red. (accept the default ReqTy)
Sales Order #2: The ReqTy is 011-Delivery requirement (accept the default ReqTy)
For the same material, sometimes the ReqTy is KSL, sometimes it is 011.
Another question is that in the ReqTy field, when F4 is clicked to show all the possible selections for ReqTy, there ain't KSL. Although there is no KSL in the ReqTy list, but KSL is defaulted in the Sales Order.
Please shine some light.
