Error in VL01N(Delivery qty is greater than target qty while taking return)

Hi Experts,

I am facing a problem "Delivery Quantity is greater than the target quantity" while doing the inbound delivery from VL01N t-code for sales returns with reference to return order.

I am trying to do the inbound delivery for the same Quantity which is in return order but still it is showing error.

I have checked my configuration and could not find any mistake under this process. I am not able to identify the error. In my delivery item category we have put "B" under over delivery check which is our business requirement.

If I remove "B" from delivery item category, i am not getting any error in inbound delivery but which is not right way of doing.

I could not find suitable query in SDN. Can any one please share your expertise to solve this problem?

Thanks in advance,

Regards
