SAP ME38 screen - Maintain scheduling agreement schedule

Hi

In Me38, the user needs additional fields on the delivery schedule screen:

CURRENT SCREEN

REQUIRED SCREEN

I doubt, if there is some authorization object linked to additional fields being displayed

Also, I read the scn posts, there are lots of user exits & BADI suggested

But, I want to be sure that, if I need to add fields via an user exit / BadI

OR

Am I just not aware of catering to the same by changing in layout, somewhere in ME38?

Best Regards
