There are three possible explanations for this error message.

1 You have imported the payroll checks already. You should verify in MultiLedger that the checks you are trying to post have not already been posted. To do this:

Click Transaction Journals in MultiLedger’s Command Center, then select the month from the month list.

Select the General radio button, then look for PR and ET entries for that date to see if checks have already been posted.

2 You are importing payroll checks with the same date as checks you have imported already. If you are posting checks that have the same date as checks you have already posted to MultiLedger, the Checks Reference # and the Taxes Reference # on the Employee Paychecks window in Payroll will be the same as the checks you already posted. You should change the Checks Reference # and Taxes Reference # and try posting again.

3 You have a General Journal transaction in MultiLedger that has the same document number and date as the payroll transaction you are trying to post. Check the General Journal in MultiLedger for a transaction with the same document number and date as the transaction from Payroll. Usually it is the ET-[date] entry that is duplicated. If necessary, change the Checks Reference # and the Taxes Reference # in Payroll and try posting again.
