Protecting a Form Tab

A form tab can be protected in the program, preventing user access to that tab when certain conditions are met. A form tab can be protected (disabled) by moving the value CRT-FOLDER-TAB-PROTECT to the AF field for the form tab.

MOVE CRT-FOLDER-TAB-PROTECT TO ProgramCodeF1-LOC-TabName-TAB-AF

A form tab can be unprotected (enabled) by moving the value CRT-FOLDER-TAB-RESET to the AF field for the form tab.

MOVE CRT-FOLDER-TAB-RESET TO ProgramCodeF1-LOC-TabName-TAB-AF

In the following example, when the Location Class "Other" is chosen by the user, the Guests form tab is protected (disabled).

001105     IF (LOC-CLASS = "Other")
001106         MOVE CRT-FOLDER-TAB-PROTECT
001107                                 TO GD01F1-LOC-GUESTS-TAB-AF
001108     ELSE
001109         MOVE CRT-FOLDER-TAB-RESET
001110                                 TO GD01F1-LOC-GUESTS-TAB-AF.

Form Tab Protection Considerations

The program should not position to a field or return a field value on a protected form tab.
The program logic should not flag all form tabs as protected at any one time.
Application program logic should not assume that a tab remains at the same protected/unprotected value that was last set by the application. Applications must protect the tab again when the transaction returns.
Form tabs that are defined as secured in Environment security are automatically protected. For more information on Environment security, see Lawson Administration: Resources and Security.
