Hi Michel,
If you have a separate storage location for production, as explained by Caetano, you can also count them these ways:
- Materials to be processed:
Open MB52 transaction for that specific storage location and material type (I assume you have different material type for the input and output materials). It will give you a picture of which and how many materials in that storage location (which is the production storage location). - Materials already processed:
It depends on how you define the materials as "processed" and "stored".
(1) If "processed" means the yields are confirmed and "stored" means goods receipts for them have been done, then you can count the processed materials by calculating the confirmed yields. Open COOIS transaction and open "Confirmation" list. You can summarize the "Confirmed Qty" to get the total processed materials for selected orders.
(2) If "processed" means goods receipts for the materials have been done to a certain storage location and "stored" means they are transferred to other storage location (ex: warehouse), then you can open MB51 transaction for the storage location in which the goods receipts are done and use movement type "101" and "102" as selection criteria. You can consider total receipts quantity as total "processed" materials ready to be "stored".
