MIGO - Return delivery to vendor - Accounting entry is wrong - Movement type _ 122

Hi Guys,

I have an issue and need your help.

User has created a PO - 1000 Qty, MIGO done for 1000 Qty.

MIRO done for 950 Qty,

User has done Return delivery to the vendor by using MIGO transaction code with movement type - 122 for the difference Qty - 50.

Now Stock overview appears ZERO but Accounting entry was wrong. Accounting entry was generated as shown below

86   GR/IR clearing   (DR)  10530.70 USD

96   Price diff            (CR)  10530.70 USD 

but correct should be as shown as below

99    Inventory        (CR)   10530.70- USD

86    GR/IR clearing (DR)  10530.70  USD

I have already replicated the same (as it is ) scenario in DEV system, accounting entry was correct.

Please help what could be the reasons for wrong accounting entry.

Thanks in advance.

Regards,

Suri
