Example 42: Adding Access-control functionality to menu-options

This post illustrates how to add Access-control functionality to menu-option MyDBKTDL (MyDaybook). This program (i.e TDL42) is an extension to our earlier program TDL41.

To understand this program, you must enable the Security features in your Company. It is advised to try out this program in a Dummy Company.

Steps enable Security Control:-
1) Open any Company (say Dummy)
2) Press Alt+F3 in the "Gateway of Tally" menu. This will bring forth "Company Info" screen.
3) Select option "Alter" and select the Company Name.
4) In the "Company Alteration" screen, set "Security Control" to YES and enter the ADMIN-name and password. Save the Company details.

Steps to Create new User:-
1) Press Alt+F3 in the "Gateway of Tally" menu and then select "Security Control" option.
2)Next, select option "Users and passwords" to create a user. Enter any Username (say ABC) and password and then set the "Security Level" to DATA ENTRY.

Steps to Assign rights to the new User:-
1) Press Alt+F3 in the "Gateway of Tally" menu and then select "Security Control" option.
2)Next, select option "Types of Security" and then disallow access to Report DAYBOOK to the User that you have created.

Summary
In the above mentioned steps, we have
a) Enabled "Security Control" in the Company Alteration screen
b) Created a new user.
c) Disallowed Access-rights to DAYBOOK report to the new User (ABC).

As you can see, we have restricted the newly created USER from Accessing the DAYBOOK Report. Now, in program TDL42, we create a new report MYDBKTDL which belongs to the DAYBOOK family. As a result, the ACCESS-CONTROL for DAYBOOK applies to MYDBKTDL also.
