How to refresh parent screen after a child process.

APPX 4.1

If a child process is invoked from an input process and the child process modifies a displayed data element from the PCF, you can instruct APPX to redisplay the parent screen by putting a DISPLAY statement (no Application Id or Field name) in the Post Invocation of the child process. The data processed in the child may have to be re-written depending on the type of child being invoked.

APPX 4.2

Starting with APPX 4.2, the parent screen is automatically redisplayed when returning from a child process. The DISPLAY statement in the child’s Post Invocation Event Point is not needed.
