Implementing BADI MD_ADD_COL_EZPS in extending MD04 transaction.

Hello Experts,

I have a query in regard to extending MD04 transaction.

Currently MD04 is enhanced with 3 custom buttons (used buttons are: BUTTON1_EZ, BUTTON2_EZ and BUTTON3_EZ)  being displayed based on which a new column gets displyed in the table control.

Now when I have to  add a new custom button, I try to use BUTTON1_PS in same implementation of BADI "MD_ADD_COL_EZPS" to display another column in table control.

The problem here is that it isn't getting displayed on MD04 screen nor can I use it from path in Menu Bar:

Settings --> User Exit Periods. Here it isn't showing in activated mode.

Kindly provide your inputs.

Regards,

Ansh
