Implementing a Regular ( Normal ) Function Module and Calling it inside a program

 

• In the previous parts, we have discussed the various tabs of a function module.
• In this part we will write the logic for a regular function module and will call it inside a program.

---

Requirement :-

• Suppose, I want to display Sales order data from VBAK table based on the input Sales Document Number.

---

Solution :-

• Step 1 :- Go to SE37 transaction code and create a function module.

  
  
  

  
  

• Step 2 :- Now, In the Import tab, we need to pass the importing parameter.

  • We have to pass range of Sales Document number therefore we will have to pass the Range table of Sales Document number in this importing parameter.

    
    
    

    
    

  • I will simply pass this range table in the import tab.

  
  
  

  
  

• Step 3 :- Go to export tab and pass the exporting parameter.

  
  
  

  
  

  • Since, we want to export a list of data, therefore I will create a associated type for it from SE11 transaction code.

  Structure :-

  
  
  

  
  

  Table Type :-

  
  
  

  
  

• Step 4 :- Now, pass this table type as a associated table type for the export paameter.

  
  
  

  
  

• Step 5 :- Now write the logic in the source code tab.

Calling Regular function Module to our Program :-

• Step 1 :- Go to SE38 transaction code ( ABAP Editor ) and create a executable program for the same.

• Step 2 :- Create a type structure and corresponding internal table.

  
  
  

  
  

• Step 3 :- Create a select option for the sales document number.

  
  
  

  
  

• Step 4 :- Click on the pattern button and call the function module and import the internal table data.

  
  
  

  
  

• Step 5 :- Display the result in form of ALV using factory and display method of CL_SALV_TABLE class.
