I prefer to use planning strategy 54. After GR from production order, the FERT will be moved from production plant to commercial plant. During this step, a existing add-on combines several steps. It make the gm311 in order to change the sales order stock to normal stock, and then make the gm301 for gm between plant. The most significant thing is to change the sales order plant.
The question arise. SO disappear from production plant. PIR can't be reduced by the later delivery as no sales order exist in production plant. I am wondering if it is possible to make an add-on to reduce the PIR? What is the potential risk caused. I don't think that I can consider all the senarios and SAP internal logic until now. I expect to get your kind advice. Thanks.
