To update / modify the details of ledgers already existing in Tally, you must use the template "Master-LedgerMaster.xls".
In the aforesaid template :
- Specify the ledger names
- Specify the details to update (example TIN No).
-
Other fields/columns which are not be changed must be kept blank.
It is advised that you first TEST-CHECK the same by updating one ledger only. If everything goes fine, you can update the remaining ledgers.
