Hi Experts,
I have the following case:
- We recive a purchase order from customer for an item, which method is "Make", and it has a BOM,
- A Sales order need to be created, and for that we have to add the Due date. As a simple case, lets say the Customer send a delivery date, when he wants the product (to be honest, in the 80% of the cases the customer doesn't send anything, he is waiting for our reply on the delivery date)
- As per the above written, we need the exact Due date of the Sales order, and that can only be determined by us, because the due date depends on our Production plan, Capacity, and from the Purchase orders we raise for our Vendors. Ok, we can do this with the help of MRP, if we run it on the Sales order, BUT,
- Due to engineering changes (see my unanswered discussion on this theme: http://scn.sap.com/thread/3583213) or quality problems, we need to add a Production order first, beacuse we need to make some changes on the BOM,
- In order to add the Production order, we have to determine the Due date of it (which we don't know, beacuse MRP can determine that, but to be simple, let's say we write in the date we recived from customer)
- After this we run MRP, and restrict Production orders to the one we created, and get the results from MRP
The problem is, that in the MRP results we do see that - for example - one component (a buyed Item) from the Production order can only come in overdue, but we don't know how this reflects the due date of the production order we ran MRP on. And there for, we don't get any suggestions on the delivery date of the Sales order neither.
Is there any solution to this? I've heard that 9.1 SAP has enhanced MRP functions, can it handle this. (We are currently on 9.0. Pl07)
Thanks in advance:
