Hi Pramod,
in ByDesign we do not have a positive pay file as you know it from Oracle, but we suggest the customers asking for the positive pay file to use the Checkbook Register report in Payment Management.
Here is an example, where I did configure a variant. The file can be saved then as csv. Please see the screenshot for the same.
If you think, that should be a standard report, then please use the ideas forum to address your request: https://ideas.sap.com/SAPByDesign/
Hope this helps. If so - please mark the entry as completed.
If not - please let me know.
Best regards
Marlene
