Withdrawal Qty from ECC not converted to Base UoM of APO

Hi Experts,

We are experiencing incorrect behavior in getting the withdrawal quantities from ECC to APO. In RRP3 Forecast tab, the Withdrawal Qty is not converted to the Base Unit or Measure maintained in APO. For example, in ECC the qty is 300 BOT, in APO it is 300 CS. What master data should we check to resolve this issue? I also noticed that the UoM of the MAT1 has a message ' Gross weight is less than net weight'. Does it have any effect on the issue? Thank you.

Regards,

AA
