MRP Deleting Storage Location Reservation over Manual reservation

Hi ,

I am doing planning at storage location AD02 for a Material and have another storage location as AD01 under plant ABCD.

In MRP 1 , MRP Type = V1 , ROP = 5 , Lot Size = HB and Max. Rep. = 15.

In MRP 4 view, I have Reorder Point planning = 5 and Replenishment Qty = 10 for AD02 Sloc.

Let us assume :

Current Stock Plant = 0

AD02 Stock = 0

After MRP run,

I am getting Stock Transfer Material Reservation no. (Say 10001) from AD02 of qty = 10 and

Procurement proposal = 25. (Reservation + Max. replenishment qty).

This MRP results are fine.

Now I created manually reservation (With MB21) no. (Say 10002) of qty. = 8. on Storage location AD02 and re-run the MRP.

Result : (not able to understand)

MRP has deleted the Stock Transfer reservation no. (10001) and result will have only

stock transfer reservation no(1002) with qty = 8 only.

Procurement proposal qty = 15

Why MRP deleting stock transfer reservation created by first MRP run and keeping only on reservation no. (10002) ???

    Hi ,

    I have updated my question. Thanks for your input.

    MRP has created stock transfer reservation (MRP Element: TrnRes) on AD02.

    Against this MRP also created Reservation (MRP element: MtlRes) .

    MRP does not create or change reservations.

    Are you really talking about reservation or do you mix this term with requisition?

    • Hello Jurgen and Dhiraj

      MRP can create stock transfer reservations, depending on the special procurement configuration.

      When you create your stock transfer reservation manually, MRP will identify it as a replenishment proposal and, since it is enough to cover the reorder point, it will delete the replenishment proposal created in the previous MRP run, as it is no longer necessary.
