Quantity Reversal and Process Order Cancellation

Dear SAPians,

I have a problem in Cancellation of Process order after doing the reversal of Quantity after UD thru following steps :-

1.Assign Inspection Type u201808u2019 in the Material master thru T-Code u2018MM02u2019 & Save.

2.Go to MB1B & Make Transfer Posting Thru Movt. Type u2018322u2019 and SAVE.

3. Now we tried to cancel the process order but system is displaying an error 'Quantity is Partially posted in UD' and we are unable to cancel the process order

Please Help

Thanks in Advance.
