Error message 6000,606
We have an AR item that had a maintenance entry (which reduced the balance), then 2 payments applied against it. At this time the balance for the item is $0. The user is now trying to unpost the maintenance entry and is getting a message to 'Unpost the most recent activity in Group BU xxx, Group ID xxx first (6000,606)'. The group id the message references is one of the payments. Why must the payment be unposted first?
