Cancelation of partial line items in the MBST is not opening the delivery

Question

Hi Gurus,
We are posting the GR with 503 mvt type with ref to delivery. In this process when some of the line items have to be returned, we are posting MBST against those line items. To cancel / reverse the same in delivery using VL09, system (does not re-open those line items) is not allowing us to cancel partial line items. Instead the entire delivery is being cancelled.
The problem to cancel / reverse the entire delivery & material document is some of the line items are are already consumed.
When we cancel/reverse some of the line items using MBST and there by cancel the material documents, system does not allow us to cancel the particular deliveriesdoes not re-open those line items). When we cancel the entire delivery, the link between the original delivery and already consumed materials is lost.
I guess this is Standard SAP behaviour and some one would have encountered with a similar problem.
Request you to check and let me know how to resolve this issue.
Thanks / Sandeep

The MBST is cancellation of material documents or in other word you are cancelling the action whic were carried out earlier.
You might have noticed that when you are using MBST and entering input parameter as material documents system by default will carry all the infoermation which were there in that material documents.
I fyou weants to cancel part of material  you can do this in MIGO sereen and select the option of return delivery and saelect the line item which youw wish to send it back or return to vendor.
For partial returns you should always use MIGO, RETURN DELIVERY against MATERIAL DOCUMENT, put in the material document No. and then whichever line you want partially return, you enter the partial quantity and save the document.
Hope this clear.
