Streamlining ALV Functionality: Setting PF Status in ABAP for Enhanced User Interaction

 

Set PF Status :-

Setting the PF status (Personal Functions) in ALV ABAP allows you to customize the function keys (PF keys) available to the user within the ALV grid. Here are a few points on setting PF status in ALV ABAP.

  1. Customized Functionality: You can define specific functions or actions for function keys like F1 to F12, allowing users to perform common tasks directly from the ALV grid.
  2. User Interaction: By setting PF status, you provide users with intuitive ways to interact with the ALV report, such as navigating between pages, sorting data, filtering, or executing custom actions.
  3. Contextual Actions: PF status can be tailored to the context of the data displayed in the ALV grid, providing relevant functions based on the user's current task or selection.
  4. Integration with Toolbar: PF status can complement the standard toolbar options in ALV, offering additional functionality or shortcuts for frequently used actions.
  5. Personalization: Users can personalize their PF status by configuring their preferred function key assignments, allowing them to optimize their workflow according to their needs and preferences.
  6. Enhanced Productivity: By providing easy access to commonly used functions directly through function keys, PF status contributes to improved user productivity and efficiency in navigating and manipulating data.
  7. Dynamic Functionality: PF status can be dynamically updated based on user actions or changes in the application state, ensuring that the available functions remain relevant and contextual.
  8. Consistency with SAP Standards: Setting PF status aligns with SAP's user interface standards, promoting consistency across different SAP applications and facilitating a familiar user experience for SAP users.

Overall, setting PF status in ALV ABAP enhances the usability and functionality of your ALV reports by providing users with convenient access to relevant functions and actions through function keys.

Requirement :-

  • We will create a custom button on selection screen.



  • Suppose, we have few details from VBAK table above.

  • so, suppose I selected a row and once I click on the button, then it should be showing corresponding line items.

Solution :-

  • Step 1 :- Create a executable program in ABAP Editor.



  • Step 2 :- Create a type structure for few fields from VBAK and VBAP table.



  • Step 3 :- define a select option to take input in range.



  • Step 4 :- Write select queries to fetch data from the VBAK table.



  • Step 5 :- Write field catalogs for the above internal table.



  • Step 6 :- Call Function module REUSE_ALV_GRID_DISPLAY.



  • Step 7 :- Enable I_CALLBACK_PF_STATUS_SET and pass a parameter, also enable I_CALLBACK_PROGRAM.



  • Step 8 :- Now, copy the above parameter I_CALLBACK_PF_STATUS_GET and double click on REUSE_ALV_GRID_DISPLAY. and click on find.



  • Step 9 :- Double click on the function module



  • Step 10 :- again find.



    • Double click on REUSE_ALV_LIST_DISPLAY



    • copy below parameter



    • now find a subroutine with the same name.



  • Step 11 :- go back to the main program and create a subroutine with the same name.



  • Step 12 :- Create a set pf status and double click on it.

  • Step 13 :- Provide a short description.



  • Step 14 :- Open the Application toolbar and give a name in it.





  • Step 15 :- double click on DISPLAY → press enter



  • Step 16 :- Press enter → double click on any shortcut key→ provide the description.



  • Step 17 :- Press enter and activate it.

  • Step 18 :- Get back to original program and enable



  • Step 19 :- now go inside the function module REUSE_ALV_GRID_DISPLAY to copy the name of subroutine for the same and write the below logic.

Understanding Different Types of SAP Function Modules: Normal, RFC, and Update

Image
  1. Normal/Regular Function Module :- It can be called inside the system. Here Pass by value + Pass by reference both is fine. 2. RFC Function Modules :- You can call from same system or from another possible. In RFC function module you can only have pass by value. In the same system if you are going to add the DESTINATION NONE’ while calling the RFC then it’ll be called in separate session. 3. UPDATE Function Modules :- This is generally used to update the database record. Update Function Module can be called from the same system. ( Background RFC / trfc / grfc ) This is used to achieve generally the SAP LUW. Some time we use from performance perspective also. When COMMIT WORK gets executed then Update starts getting executed. Important Questions on Update Function Modules :- When Update function Module gets Triggered ? ON COMMIT WORK IF a update function module gets failed, under which transaction we can see that ? OR What is the T-Code for ...

  Function Modules :- It is a modularization technique. The transaction code to create a function module is SE37. To create a function module, we need to create a function group. Function Group :- Function group is a container for the function modules. The transaction code to create a function group is SE80. A function group can store up to 99 function modules. Requirement :- let’s create a function module for sum of two numbers. 1. Creation of function group :- Step 1 :- Go to SE80 transaction code → Object Navigator. Step 2 :- From the drop down select function group. Step 3 :- Give a name of function group. Step 4 :- press enter. Step 5 :- Click on yes a popup screen will appear. Step 6 :- Give short description → press enter → Assign package and transaction request and press enter. Step 7 :- Right click on function group and click on activate to activate the function group. Step 8 :- You will see two includes, will be added afte...
