Some common Sage MAS90 and MAS200 errors when trying to print checks is “Check printing in progress”, “other check printing in progress”, or “bank code in use by another task”; when in reality there are no checks being printed nor is anyone else in the system. This error will not allow proceeding any further and will prevent you from printing checks.
Accordingly, a solution is the following:
1.Verify that nobody is printing in Payroll nor Accounts Payable
2.From the main menu, select File->Run
5.Select the Bank Code receiving the “in progress” message
7.When the warning message comes up, click YES
8.Continue with check printing
