Implicit Enhancement in F4_FILENAME function module

 

• We have a function module F4_FILENAME which is used for selecting a particular file from our local system.

  
  
  

  
  

• So, when we execute this function module.

  
  
  

  
  

  • We can see, we will get a pop up screen which will navigate to file in our local system.
  • In the Title we can see we are getting Choose file as Title.

  Requirement :-

  • Now, Suppose user wants to see some other title at the same place.
  • So, we will use implicit enhancement for the same purpose.

---

• Now, If I go to the source code of this,

  
  
  

  
  

  • I can see, in Title parameter text-005 have been passed, so we have to change this field’s value.
