Hi Konstantin,
Thank you for the response, finally i have got that solved. I found an other way to do it directly in the PFCG, their is an SAP Note which explains this 1628666 .
How ever i still did not get an overview on how to restrict the Delete option in the Manage substitution rules, which is the example provided by you. Is there a way for doing it?. Because i have some requirements of that kind where i have to disable some options.
Regards,
Pavan.
