Error correction flag reset for & items

What causes this issue?

In &V1& invoice items an error correction indicator was set, even
though no differing quantities or amounts were entered.
This indicator had no effect and was therefore deleted by the system.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you change an error, you must change the values as well as setting
the error correction indicator.
