Disable Delete Characteristic Combinations button in tcode /SAPAPO/MC62

Hello Gurus,

Is there any way to disable the "Delete Characteristic Combinations" button in tcode /SAPAPO/MC62 ?

I tried this by creating a test role and with a test user but not able to disable that Delete button in that tcode. Basicly, this tcode /SAPAPO/MC62 is for Maintaining Characteristics but our functional team doesn't like that Delete button.

Please advise.

Regard's,

Salman
