Hi, JH,
Would you confirm both the version and the release date of Adagio Receivables you are using?
An invoice entered and posted in AR, whether for a positive or negative amount, will show in the Customer's transactions in either Current or Historic Transactions. It is possible that, if a period end had already been and the invoice transaction been moved to history, a user could then run the Clear History function for that customer and the transaction could be cleared from that customer's transactions (along with all other historic transaction up to the clearing date selected).
If the transaction had been posted, wouldn't you have a record of it in an AR posting journal which would show the subsequent GL entries that were to be made?
If the transaction had been posted in AR and retrieved to GL, you would no longer see the transaction in the Print/Consolidate GL Transaction report. However, the G/L batch listing would show the both side of the entry to be made when the G/L batch is posted -- the CR to AR and the CR to the offsetting account.
You can always try doing the same thing using Sample data and see what the outcome is.
