Thank you for your reply Karin. I checked we do have SAP ILM license.
When i use transaction ILMARA it takes me to the link below and the webpage does not give anything.
http://hostname:8000/sap/public/myssocntl?sap-client=100
I also went in to ILM RM-Admin cockpit -->Audit Areas-->clicked on Process Aduit area and it again took me too the same link and did not nothing.
Any thoughts?
