Material in Reservation - Refurbishment Order

Hi,

Please guide me how to change the BATCH of a split valuated material in the reservation created by Refurbishment Order.

Actually by using the refurbishment order, a PR and a PO is already created and Receiving is already done.

Now we came to know that user did not enter the correct batch of the material whoes reservation is created now.

Please guide me, how to change and correct the batch of the material entered in the Refurbishment Order now.

Thanks and Best Regards
