Positive Number Validation for Check Numbers

When you use the Generate Check Payments task, you can only enter positive, whole numbers for the Start Check Number and End Check Number parameters.

By default the positive number validation is enabled on the two check number parameters of the delivered Generate Check Payments task. The validation ensures that these two parameters only take positive numbers without any decimals, alpha characters, special characters, or comma separators. This validation takes place when the parameters are submitted.

If you enter an alpha-numeric Start Check Number and submit the flow, an error message displays asking you to enter a positive whole number in the Start Check Number or End Check Number field.

For user-defined flows, use the Positive Number display format type for these two parameters to enable positive number validation.
