SAP Note 22733 - Canc. in SAPLV61A with field overflow XKOMV-KDIFF

Symptom:

Field overflow in field XKOMV-KDIFF in program SAPLV61A

Cause and prerequisites

Between the order entry and the order modification, the pricing procedure was changed to the effect that, for example, the value-added tax condition got a new level number and, as a result, there are items with different level number for this condition.
You can recognize this by the fact that this condition is displayed twice in the header condition screen of the sales order.

Solution
In this case, you can change the ship-to-party in the header partner screen and then change it back again. As a result, the taxes are recalculated and the error disappears.
If this does not work, you have to carry out a new pricing for the document.
