Payment Terms
So as an example, if invoice date was 13th Jan 2013, plus 45 days takes you to 27th Feb, so payment date would be the last day of Feb, the 28th Feb.
If invoice date was 15th Jan 2013, plus 45 days takes you to 1st March, so payment date would be 31st March.
We have Oracle R12.1.3 and cannot see how we can set this exact process up.
