Chapter 5: A Typical Input Process
Previous Activity (F4)
The PREVIOUS ACTIVITY option, activated by pressing F4, allows you to recall the screen that immediately preceded the current one. In our example, if you select PREVIOUS ACTIVITY while on a line item, you redisplay the order record for that line item. Even if you are in a scrolling line item process, selecting PREVIOUS ACTIVITY while positioned on any of the line items returns you to the order record. This option allows you to step back one screen at a time.
