Purpose:
To prompt for user actions within SAP screens and nest the process functions to reuse them. The maximum nested level is 8.
Pre-Requisites:
1. Liquid UI WS.
2. Liquid UI WS Server version 3.5.570.0 & above. (if accessing scripts via WS Server)
Usage:
To trigger a process function using parameters. This command is often used in conjunction with the "onscreen" and "onUIEvents" commands. The perfect use case for "reenter" is "MessageBox" command in LUI Server.
Syntax:
reenter('tcode',{process: functionname, using:{parameter:value}});
Options:
fcode/tcode: Passing SAP transaction code.
process: Calls a function.
using: Passing values to processes.
Liquid UI Code:
Below code demonstrates the usage on SAP Easy Access Screen.
