urgent question: validation of vat rate in ReIM detail maintenance form
as I am trying to set up a vat increase for a particular country, I would like to understand, how ReIM (version 13.0 preferred) is validating the vat rate during the manual setup of an invoice.
As far as I know, you can choose in the ReIM invoice detail maintenance form for setting up invoice details if you want to set up the detail manually or choose it as offered from order/shipment. Let's assume I choose manually, then I have the possibility to use a dropdown box where I can see the possible vat code - vat rate combinations. By which validation those values are offered? Is the invoice date from the invoice head maintenance form relevant? Or is the sysdate/vdate used for finding the current vat rate? Or is it the procudure one I did not mention?
