Payment Method not changing in sales-credit memo (accounting document)

[sagar_kapadia]

Hello,

When trying to change payment method (BSEG-ZLSCH) field in sales related credit memo - accounting document, Even though the document change rule permits entry in the payment method field, message F5303: 'No changes made' is displayed when saving. When displaying the document again, it turns out that the entered changes are cancelled again and the old value is displayed.

Is this a normal system behavior?

Which transaction, screen, field value are you trying to change? A screenshot would make it a lot more easier to understand the issue.
