Specify Screen Properties for Repeating Groups

If you add repeating groups, you use the Detail and Screen Properties commands to specify screen properties regarding scrolling. You have the following options:

• Allow scrolling. Scrolling lets the user scroll back and forth through a repeating group. For nested repeating groups (repeating groups within repeating groups), scrolling occurs on the highest level group. Multiple repeating groups placed on the same screen scroll synchronously.
• If the maximum cardinality of the entity represented by a repeating group exceeds the number of display lines, you should allow scrolling. If the cardinality is equal to or less than the number of display lines, scrolling is not necessary. The same is true for nested repeating groups.
• Allow or prevent the updating of unused occurrences of a repeating group. This prevents a user from scrolling forward when the last filled-in occurrence of the repeating group appears on the screen. If the user attempts to scroll forward, the NEXT command is sent to the procedure. If the unused occurrences are protected, the user cannot add occurrences to the end of the group. The default option is leaving unused occurrences unprotected to allow updates.
• Select which occurrence in the repeating group will be displayed on a return from a link. You can choose to redisplay the screen that was displayed before the link, or you can display the screen with the first occurrence in the repeating group. If you select the screen that was displayed before the link, you must have the dialog flow returns on properties set to Display First. The default option is the first occurrence in the repeating group.

You can select these options from the same panel.
