service call to function module not fetching updated data

Hello Experts,

I have developed one web dynpro application from which I am making a service call to Z function module. This function module call is triggered on click of a button from user interface.

Now, suppose my web dynpro application is loaded in the browser. At the very same time, SAP user updates the relevant data to function module, using the standard transaction in system. Now if function module is executed using tcode SE37, it returns updated data.

But when same function module is triggered on the click of button from the application which is loaded in browser, data values returned are not updated.

I am very surprised by the behavior of this. Help me get through this.

Regards,

Harsh
