Creating Simple RFC

Go to SE37 to create simple function module which will return a simple calculation. We will pass a value tothe webservice and that web service will call the function module in SAP and return that value to Flexapplication.

In the Import Tab we are importing a Data with Type Integer.

In Export Tab FM is returning the calculated value.
