• Message class: L3A - Messages on Transfer Order Kernel

• Message number: 029

• Message text: You are not allowed to create a difference quantity in this transaction

What causes this issue?

Because the issuing plant-storage location combination is still flagged
in the handling unit, whereas the delivery already contains the
receiving plant-storage location combination, the system cannot decide
to which plant-storage location the difference entered should be
posted.

System Response

You cannot confirm the transportation order with a difference quantity
in this situation.

How to fix this error?

If you want to debit the difference from the issuing plant-storage
location, remove the handling unit from the inbound delivery and
process the difference in the issuing plant-storage location
combination. After this, you can assign the handling unit to the
delivery again.
If you want to debit the difference from the receiving plant-storage
location combination, you should first post the goods receipt, then
process the difference in the receiving plant-storage location
combination.
