Information in display and alter is the same, hence only alter is discussed. Display option does not permit any modification. Alter option is accessible only to authorised users.

You are allowed to alter any information of the ledger master with the exception of the Closing Balance of a ledger account, if any, other than closing balance of accounts under the group 'Stock-in-hand'.
Please refer to Advanced Usage for specifying closing stock values.
Deleting a ledger account
You can delete a ledger from the alteration mode by pressing <Alt>+<D>. Tally does not allow deletion of accounts that have transactions. Therefore, should you wish to delete an account, which has transactions, you must first delete all its voucher entries.
