When user try to settle invoice and payment with different remittance address, getting an error:
The remittance address on the selected transaction line does not match the remittance address on the selected payment journal line. Change one of the addresses to mark the lines for settlement.

We would like to get a possibility to disable this validation.
Maybe in next releases it can be taken as a feature which give Companies possibility to decide if it's important to check remittance address or not.
