Calling the RFC Function Module via RFC Destination

 

Requirement :-

• We have created and RFC function module in the previous part and then we created a RFC destination for the same.

Solution :-

• Step 1 :- Go to SE38 transaction code and create a executable program.

  
  
  

  
  

• Step 2 :- Create the type structure and corresponding internal table and work area for the same.

  
  
  

  
  

• Step 3 :- Create a select option to take range of inputs from the user.

  
  
  

  
  

• Step 3 :- Now we will the call the function module and will pass the destination name for our function module.

  
  
  

  
  

• Step 4 :- Now we can display the data in form of ALV using CL_SALV_TABLE class.
