can any developer can develop tdl for hsn / sac code , just like ledger / stock item , we can create master for hsn / sac code & its hsn /sac code description, so when we create / alter stock item , in hsn part, when we go to description - than list of description should pop up & we have to select from list of description which must show list of description along with respective hsn / sac code, so when we select hsn description than its respective hsn /sac code get auto fill , but it can be alter if require this hsn code should be printed in invoice & also we can alter it hsn module , so please develop this tdl it is very useful & productive & will speed up entry & also mistakes.
