Many thanx, once again.
You are right, i have not explained my self correctly.
The situation is as follows: my plants run their MRP and they produce their purchase requisitions. Let's assume plant A requires 10 items of material B, which MRP creates a Purchase requisition for towards the supplier. Now, let's assume this material is also in plant C.
How can i run availability check and under what rules so as i take this material (through internal stock transfer) from plant C and not purchased from the supplier?
Of course, i will have to implement rules so as (a) plant C does not run out of stock and (b) that it would be cheaper to take material B from plant C and not from the supplier.
Best regards,
Nikos
