Invoice Receipt Update Commitment Value

Hi PS Expert,

We run project system(PS) module and update commitment and actual values. We also apply sap notes to move commitment update from purchase requisition to purchase order. Then, our customer also request to update commitment value in stock transfer order creation. Hence, we apply badi as per instruct in sap notes 604033.

Our problem arise when we apply above badi, during logistic invoice verification(LIV) against STO with freight cost, the freight cost amount update back to commitment value.

Is this a standard behaviour or any setup missing?

Thanks before,

Regards,
