¿Qué causa este problema?

By changing the item, the +/- sign of the payment amount would change.
The payment method defined could therefore no longer be used.
If the item is contained in a zero clearing, a total other than zero
would result after the change so that the zero clearing could not
longer be made.

Respuesta del sistema

The change is rejected.

¿Cómo arreglar este error?

If you want to change several items within a payment, check whether the
changes can be made in a different order.
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
then the invoice. The payment amount then changes from 950 to 1050 and
finally to 50. The reverse order is not possible because a payment
amount of 50- would result as an intermediate value.
If you cannot avoid a change in the +/- sign for the total amount, you
must first of all block all the items using the "Block all" function
and then release the items which are to be paid individually. You can
then also define a new payment method (for example, incoming payment
instead of outgoing payment or outgoing payment instead of zero
clearing).
