PP Interview Questions & Answers

Split planned order during MRP run by production version?

We have 2 production lines within one plant to produce the same  finished  product.  For  planning, we  put  the  planning quantity for finish product in Demand Management with a daily planning period and differentiated the production line with a production version. The problem occurs when we run MRP. The system automatically accumulates the requirement in a same day demand. Hence, we need to automatically split the planned order with a different production line. Since the lot size range is the same, is there a more efficient way as to how we can split the planned order?

If you want to split the planned order by percentage, you can use quota arrangement (meq1). If you want to split order by capacity, then you might want to use fixed lot size, and finite capacity with option “ changing
production version on error”.

( Not all negative quantity items fall under these categories!).When BOM is created for FERT , you can see one indicator in COMPONENT DETAILS screen for co-product.You need to define the co-products with this special indicator .
