Hi Farooq.
Please follow the following steps and see whether you can change the email text per your wishes:
1. Login to the PAM-UI
2. Goto 'Library'
3. Select 'CA SLCM' in the left-hand navigation
4. Select/Open 'SLCM_GlobalMessages' (double click on it)
5. Expand 'asynchronousSoapOpMsgs__'
From here, you can checkout and change per your wishes and checkin again.
Please let me know whether this then works for you too?
And we then may close this case accordingly.
Thanks in advance and kind regards, Louis.
