3.0 Commission is missing for a salesman for a work order.

First, ensure that the salesperson is entered on the sales document. You can ensure this is the correct, or expected, salesperson by accessing Customer and then checking the salesman setup on the marketing tab. Then you can verify the accounts the work order posted to by accessing the accounting distribution pop-out from the work order under the inquiry tab in the top taskbar.  

Second, make sure that the GL accounts the invoice is posting to is set up for commission to be paid to that salesperson.

This can be verified in the application by accessing Zip Code Setup and then the icon with two people.  Select the salesman from the drop down and make sure the GL accounts are listed in the grid.

Finally, if your company allows for invoice date adjustment (backdating the invoice), check the invoice date of the work order to make sure you are running the report for the correct date.  For example, if an invoice was closed on December 2 but was backdated to an invoice date of November 30, the commission would pull into your report for November and would not be included on the December report as the report uses invoice date to determine the work orders to include.
