The following error message has been encountered when trying to allocate credit notes or receipts in the debtors console:
Manual Allocation:
Invalid column index
OK
To fix this manual allocation error, complete the following steps:
Open the Debtors Console.
Select the client with the problem.
Click the Allocate button.
From the Edit menu bar, select the Synchronise option.
If this doesn't fix the problem, then from within the Edit menu bar option, select Unallocate All, followed by the Auto Allocate option. Note: Some Practices have certain invoices allocated to specific receipts. Hence, you will have to manually reallocate the transactions after doing this.
Close out and reopen the Client Maintenance window and select the same client.
