I had experience with PIR upload using Requirement Plan, I worked with requirement type BSF and LSF there was no issue. But Currently we are using Z Planning strategy which is copy of 50. the requirement type is VSE and description is changed as "Preplanning w/o Assembly.
In MD04, the description of Strategy below which all MRP elements like PIR will come, is changing like " preplanning GPEOFCST" where GPEOFCST is Requirement Plan name.
But if I enter PIR at Material level (without Requirement Plan) description is as same as Strategy description. I feel there is no impact on functionality but visually its impacting the description.
Please find the attached document with screen shots. and let me know your comments.
