When checks are set up for Direct Deposit, will Mekorma MICR generate a duplicate?

No. Mekorma MICR is fully integrated with Direct Deposit. If Direct Deposit is set to print Earning Statements as voided checks, they will print as part of the check run using the MICR format. If Direct Deposit is set to print Earnings Statements separate from checks only, the checks will print during the MICR check run. The Earning Statements will print after the checks using the regular Dynamics GP report.
