Payable transfer tO GL

Hi All,

payable transfer to GL

source :spreadsheet, manual.()

as a devloper i need to test a condition for duplication (payable transfer to gl)

i have generetd some invoice manulaly and ran the Payable transfer to Gl program and it got sucessfully reflectd in Gl.

now further i need to check whether this progarm is capable of detecting duplicate invoice or not!

payable transfet To Gl is seeded program and i am not sure how to check this dupliaction logic.

earlier i tried to create a invoice with same name and detial there it is giving error as this name is already exesting so i cant run the program for same invoice.
