I am able to put in my own posting description that I can use for reference later. I went to look up a posted purchase invoice to get that information and it is not available anymore. I cant personalize it to show up on the invoice either. I went back to the list of posted purchase invoice to get it and it wasn't there either. Please don't remove it from the invoice after posting, or from the list of posted purchase invoices, or from the list of purchase invoices. I checked posted purchase credit memos and same thing is happening with those.
