Hi Pradeep ,
Can you please check whether MASTER privileges associated with the Privilege Repository is assigned to the User ((PRIV:ONLY , PRIV:SYSTEM:,...) Privileges , along with the Account Attribute)
If System , Account Privilege does not exist , try assigning the same & do a removal after the same .
Also , Can you check what AUDIT Table shows around this Link ID .
Thanks ,
Jerry George
