Dear Experts, I am trying to do Tally integration with a third party application. I am using just one xml request to create Masters, Delete existing system generated voucher, and creating new vouchers. In case there is some error in my request or any other error , I want none of the above actions to be executed. Unless all the action can be successfully performed i don't want to any changes made in existing data in tally. Is there any way of ensuring this within my xml request or any other way ? Plz help!
