Why are the same payment numbers (EFT or Check) printing for multiple payments and/or vendors?

If the EFT or Check numbers are listed multiple times and for multiple vendors, please ensure the following:

 

1. The GP checkbook maintenance window does not have the allow duplicate check numbers check box marked. Note:  This also impacts the assignment of EFT numbers.

 

Note:  Dynamics GP assigns check numbers and EFT numbers to payments. Mekorma inherits this functionality.
