By Default in Tally if any user has daybook access then he can see Summary of all vouchers for that period in Day Book Report. This add on facilitates Admin to control the Access of Day Book Vouchers. Admin can restrict the User to View Other Users Created/Altered Vouchers. He can view only his created/altered vouchers. User cannot see or alter vouchers created by other users. Admin can give Access to view All Vouchers to Authorized Users through Security Control.
