Dear Experts,
I am having this the following scenario which I would like to ask if someone has come across on.
We are using EX (Lot for Lot Order Quantity) with the Minimum Lot Size and Maximum Lot Size set as 0.
Original data in MD04 Rec./reqd Qty Available Qty
-
Stock 0
Production Order (PrdOrd) 459 459
Order Reservation (OrdRes) 459- 0
Production Order (PrdOrd) 53 53
Order Reservation (OrdRes) 53- 0
Production Order (PrdOrd) 105 105
Order Reservation (OrdRes) 105- 0
Everything is fine as the every order requirement has been fulfilled with a Production Order. These Production Orders has been converted from Previous Planned Order
The Production Planning Department then inserts a Production Order at the top of the chain. Which is as follows
Updated data in MD04 Rec./reqd Qty Available Qty

Stock 0
Order Reservation (OrdRes) 1000 1000-
Production Order (PrdOrd) 459 541-
Order Reservation (OrdRes) 459- 1000-
Production Order (PrdOrd) 53 947-
Order Reservation (OrdRes) 53- 1000-
Production Order (PrdOrd) 105 895-
Order Reservation (OrdRes) 105- 1000-
Now we run MD01 again to generate the MRP Requirements and the following is the output generated
MD04 Data after MRP Run Rec./reqd Qty Available Qty

Stock 0
Plan Order (PldOrd) 383 383
Order Reservation (OrdRes) 1000 617-
Production Order (PrdOrd) 459 158-
Plan Order (PldOrd) 459 301
Order Reservation (OrdRes) 459- 158-
Production Order (PrdOrd) 53 105-
Plan Order (PldOrd) 53 52-
Order Reservation (OrdRes) 53- 105-
etc....
The SAP system creates a Plan Order at the top of the list. But I would like to ask why the Quantity is 383 instead of 1000 which fulfills the Production Order of quantity 1000 which is newly inserted.
Thanks.
