How To Fix 8A500 - Change not allowed - change payment amount in group & & &

• Message type: E = Error

• Message class: 8A - Messages for Argentina

• Message number: 500

• Message text: Change not allowed - change payment amount in group & & &

What causes this issue?

By changing the item, the +/- sign of payment would change. The payment
method provided could thus no longer be used. The payment affected is
not the one being edited, but a different one which contains an item of
the central invoice to be blocked.

System Response

The change is rejected.

How to fix this error?

If you want to change several items in payment, check whether the
changes can be made in another sequence.
For example, if an invoice of 1000 and a credit memo of 100 are
contained in a payment of 950, you can block the credit memo first and
finally to 50. The reverse sequence is not possible because a payment
amount of 50- would result as an intermediate value.
