Thanks Madhu.
I just followed the step and maintained ZREQUEST_REASON as it was asking me to add on Y*/Z* namespace
Now the content of the email I had received is below which did not pick up the GRC request description
Dear XXXXXXX,
A security access request # XXXX has been submitted to grant you access to XXXX.
This request requires approval from your manager and a number of role owners. Once all approvals are complete you will receive an automated email that this access has been granted.
Additional information:
%ZREQUEST_REASON%
Best Regards,
SAP Access Control Team.
How does it pick the extra variable we add?
Does it require some changes in standard program/code?
Looks like we have a missing link here.
