Whenever we generate the table maintianence, SAP generates some new
code and use the Shared code for the Table maintainence generator. Since
long time, I was wondering how can I add my own custom PF buttons in
the table maintainence screen which comes in SM30. Today, this
discussion in the SDN form raised this point in my mind again – Adding Custon button on Maintainance View.
I have started searching the GUI status in the Function Group which I
have provided in the Table maintainence generator, but I didn’t find it
in the object browser (SE80) of the Function group. So, I thought this
must be taken care by the Events in the Table maintainence. I searched
the list and I found suitable one – ST (GUI Menu Main Program Name).

To add a custom button we need to follow couple of steps: 1. Create Table Maintainence. Obviously
today’s discussion is based on the Table maintaince, we must have that
before we start it. For a information purpose, I will attach a screen
shot of the Table maintaince.
2. Copy user Interface of program SAPLSVIM to our FG We
will copy all the user interface of the main table maintainence program
to our Fuction Group. Table maintainence runtime uses the user
interface from the program SAPLSVIM. So, we are unable to find any user
interface in our FG. There will be one popup of language compatability, which you can pass it on by pressing Enter.
3. Add Custom Button in the PF-Status Here we
need to identify the proper PF-Status from all the statues. We will use
the EULG pf-status which is being called when you enter in SM30 with
Change mode. We will add the button with code “0POPUP” We can simply
check which pf-status is being used in the each screen of the SM30 by
going System > Status > GUI status. We will activate the changed
status.
4. Add Event ST in the Table modification Events Open
the table maintainence generator screen and follow: Environment ->
Modification -> Events. Select ST from the values and enter the FG
main program name. For this example SAPLZTEST_TABLES.

5. Add PAI module in the Screen Now, we need to create a new PAI module in the Screen flow. We will create the module 0CUSTOM_PF_BUTTON in the Screen. We will create this module in a New Custom include by selecting it from the popup.
In this code snippet, I am showing how to handle our user command.
Here I am just giving information popup when user interact with the
button in the change mode.

Don’t forget to activate the Function Group, since we have created a new include in it.
