Update vendor payment
From Protemos Wiki
Click "Update" to go to the Update payment details page:
Here you can change the following payment details: Legal entity, Payment method, Paid at, Amount, Currency, Note, PDF page size and orientation:
Note: You cannot change the vendor, so if the vendor is wrong, the only way out is to delete the payment and create a new one.
If you need to unlink or link invoices to this payment, it can be done on the Linked invoices section.
