Billing Invoice created & posted to GL 4/11/19 acctg dt; Discovered in June AR Group was Not Posted;

A Billing Invoice was created (from Contracts) and the BI entries were posted to the GL with accounting_dt 4/11/19. The AR Group was created with just this one pending External item. However, the "Batch Standard" was not selected as intended and the user didn't notice that the status was 'Not Posted' until in June 2019. Therefore this item was not posted to the customer account.

 

Now, they tried to change the accounting_dt on the Group to 6/21/19, select Batch Standard and run ARUPDATE. This resulted in the ACTPD error on the Pending Item. The Accounting Date on the Pending Item1 page is 4/11/19 and it is grayed out so it cannot be changed. Now the status is 'Errors' instead of 'Not Posted'
