It seems even in AX 2012, user cannot edit the already posted sales Invoice. We have a requirement from the customer that they often requires adjustment in the Sales Invoice because either tax was not calculated properly (and customer refuses to pay) or consolidated Invoice will be sent for some extra charges which were realized later.
Two questions:
1. What is the best way to adjust the already posted Invoice against sales line (or order) ?
Notice that, we only want to adjust financially (monetary value) and not the quantity.
2. What is the best way to send consolidated invoice (i.e. for extra charges which were realized later) for multiple sales order (which are already invoiced) and is it still possible to tie this consolidated Invoice against the multiple original Invoices ?
Thank you in advanced.
