How to edit or delete a Entry in Table RSADMINA?

Dear Experts,

I am trying to edit the entry in table RSADMINA required as a customizing step for setting up BW client. But, I see in table, the menu Table Entry -> Delete Entry is deactivated. Even I don't see any option in debugging mode to activate the Edit option for updating the table entry.

Any ideas, please?

Thanks & best regards,

Sreenu
