If the setup requires coverage calculation by dimension inventory status, there appear data sets on net requirement with empty inventory status. This is very difficult to understand by the customer and also difficult to explain. There should be a solution to prevent empty inventory status in coverage calculation regarding BOM-lines.

I see different kind of possible improvements:

1. Definition of a inventory status on BOM-line (master data)

2. if no definition of inventory status of BOM-line: inheritance of inventory status depending of requirement (to producing item) (this might be not so easy, because of multi-level BOMs)

3. Parameter "default inventory status for coverage calculation"
