Keep advanced procured material in project stock
We have a material with procurement key "F" and individual/collective (mrp4) setting "individual". We are use the project builder with a component created for purchasing the material in advance. In the project builder we are using procument type "preliminiary purchase requisition WBS element".
When the PREQ is created as the same time reservation is created with movement type 281 to issue the material.
Our understanding is that this way of working was keeping the received material in project stock until a new requirement was created in the project builder for consuming the project stock. We create later a simple reservation for a material produced in house with the advanced procured material in the bill of material.
We now see ywo reservations for the material in the system, one from the advanced procurement and one from the in-house reservation. This is not what we want.
