How to skip authority check tcode XK01, XK02

Hi guys,

I'm facing a issue related to authority check tcode as bellow, please let me a suggestion:

Requirement from my customer:

One user haven't authority on tcode XK01, XK02 but can update data through a Zprogram(use BDC to call transaction XK01, XK02).

I have created BDC completely but when executing, the system show error message about authority.

Please suggest a user exist or workaround to skip this authority check step.

Best regards,

DucTV.
