Hi, we have SAP Retail and we usually use transactions MM41/MM42 to create and maintain articles. In this transactions we also set data for replenishment in the 'Logistics CD' and 'Logistics Store' specifically in MRP Type (we use RS type), coverage, target stock, and others fields. Every day we run the transaction 'WRP1' for replenishment so SAP calculates our neccesity and generates purchase requisitions that later become purchase orders. This procedure has been working succesfully during 2 years.
Recently our company has open a meat production plant in our main supplying center and because we need to produce material from other materials and take care of the detailed costs we have to use the co-product characteristic. The issue here is that SAP Retail doesn't handle co-product feature and the only way we could accomplish it is using transactions MM01/MM02 to create the materials besides CS01/CS02, C40N and others related to this process.
We have realize that if we create materials with MM01 we cannot modify it with MM42 and viceversa and we've also realized that we can't set the target stock with MM01/MM02 nor the coverage we need to set if we use MRP Type 'RS', or another which requires the same data in order to WRP1 create a replenishment proposal. We know that we could use transactions MD01, MD03 and MDBT to generate replenishment but our work depends entirely from WRP1 and we don't want 2 procedures to execute replenishment. Our goal is to use WRP1 to generate planner order or production orders directly setting the procurement type 'E' or 'X'.
So, the question here is; how do we set target stock and coverage in MM01/MM02 when using 'RS' or any other Retail Replenishment MRP Type? or better yet; how can I handle this situation?
Thanks in advance.
