Authority-check doesn't work on background execution

Hi experts,

I have a question concerning the authority-check on specific authorization object which controls the resullt of transaction FBL5N.

there is a difference between foreground and background execution.

I get the expected result using a foreground execution.

Would you tell me why the autority check doesn't work on background execution and what can I do to have the same results.

thanks a lot for your help.

Kind regards,
