Hello All,
I have resolved this issue, using the new repair assignment feature that is going to be available with IDM 7.2 SP8. For pre SP8 version, you will be able to get the database objects from SAP.
Firstly the issue was the ACCOUNT%$rep.$Name% attribute was not created for AD repository of the user, which I have resolved my self.
Then for provisioning the assignments I have used the repair assignments. The detailed steps I have followed are mentioned in my blog on this. I will share the link for the blog once it is approved by moderator.
Thanks,
Krishna.
