Hello Alessandro,
Thanks for the reply,
We have already referred this note as the authorizations already assigned to user through common role.
The same user still able to access firefighter through GRC system using GRAC_SPM tcode but the error is coming when he tries to login plugin system using transaction code "/GRCPI/GRIA_EAM"
Thanks to provide some views on this.
Best regards,
Nagarjuna
