F12 Configuration Menu

F12 configurations are application centric configurations that are present across all screens of Tally.ERP 9. These configuration can be changed and managed any number of times to suit changing needs. For example, if you want to record your purchase transactions in debit/credit mode, the same can be set in the F12 configurations.

Configuration options, affect all the companies maintained in the same Tally.ERP 9 directory and setting the configuration for one company will affect the configuration of other companies in that particular data directory.
