10.11 Get the message, message type, message number, and message id using _message, _msgtype, _msgno, and _msgid

Prerequisites

• Products: Liquid UI WS, Liquid UI Server or Local DLL, Client Software
• Commands: onUIEvents(), enter(), _message

Purpose

You will learn how to find the id, number, and type of an SAP message displayed in any transaction. The three system variables associated with the SAP message are _msgid, _msgno, _msgtype. These variables are useful in error handling scenarios and to conditionalize scripts based on their values. We will walk you through the following steps:

1. Open Create Material: Initial screen
2. Perform enter
3. Add a function to display SAP message details

//Create this file inside your script folder for customizing Create Material screen: SAPLMGMM.E0060.sjs
//Now let's start adding the content to the above file

1. Add an OnUIEvent command to execute a function on performing enter.
   

   // Executes z_message process on performing enter
   onUIEvents["Enter"]= {'fcode':"/0",'process':z_message};
   

   
   
    
2. Add a function to display SAP message details on the console window using println statements.
   

   //Creates message to display message details
   function z_message()  {
   enter();
   onerror
      if(_message){
         println("Message: "+_message);
         println("Message Type: "+_msgtype);
         println("Message Number: "+_msgno);
         println("Message ID: "+_msgid);
        }      
     }
   

   
   
    
3. Navigate through the Create Material: Initial screen(MM01) and click enter on the Create Material Initial screen without entering any values on the fields.
   
    
   
   
   
    
4. You will see the error message on the status bar and message details displayed on the console window.
