authorization Issue with AR01 while executing through a Variant

HI Experts,

I have a user who is trying to execute AR01 with a variant created by user. when user tried to execute it gave a message No Data maintained.

I tried the same with a test user giving SAP_ALL, i got the required data. so I ran a trace on the end user, there was nothing which i need to do because all I got on Trace is RC=0 i tried the same with the test user (with SAP_ALL) it also gave the same Trace log.

but why is it failing for the end use?

any help is highly appreciated

Thank you in Advance.
