Passing parameters to pushbuttons

In the following section, we will demonstrate how to pass some user-entered data to a function that is called by a pushbutton. This process works essentially the same regardless of what type of screen element is being used - parameters can be passed to a variety of screen elements. In the following example, we will pass the parameter 'z_ord' to the function called by the pushbutton. In this example, the value will be entered by a user.

Go to the VA01 screen in SAP.

Open the VA01 script file (SAPMV45A.E0101.sjs) and enter the following code. Create the file if it does not already exist.

 pushbutton([1,1], "@2L\\QLaunch VA01@VA01", "/nva01", {"size":[1,10], "process":test1, "using":{"param1":"&V[z_ord]"}});
textbox([2,12], [3,24], {"name":"z_ord"});

Now create the function that you will call when the pushbutton is pressed. An example is shown below:

 function test1(param) {
                onscreen 'SAPMV45A.0101'
                set("F[Order Type]", param.param1);
                enter();
}

Save your changes and refresh the SAP screen.
The VA01 screen now appears as follows:
Enter RO in the textbox and click the VA01 button to initiate the function.
