User Interface

//Create this file inside your script folder for customizing the SAP Easy Access screen. SAPLSMTR_NAVIGATION.E0100.sjs

//Now, let's start adding the Liquid UI script to the above file and save it.

1. Add the following script to the file and save it.
    

   // Open the file up
   openfile("filenames.txt", {"delimiter":";", "output":true});
   name1 = "John";
   name2 = "Nancy";
   name3 = "Alexander";
   
   // Append to the file, set the variables you want to carry over as true
   appendfile("filenames.txt", {"name1":true, "name2":true, "name3":true});
   // Always close the file after
   closefile("filenames.txt");

SAP Process

1.  Logon to SAP and execute the script. Initially, our .txt file will be blank, and after executing the script, the file will be opened and appended with the data, as shown in the following image.
