Hi All,
Just thought of sharing for anyone else who would face the same issue:
Go to source system and find your DB connect SS. right click and go to conn parameters. Look at the USER ID and now ask your DBA to give access to the Table your Data source is trying to pull the data.
He would ask whats the User ID, give the one you found from above way.
In other words, its a permission issue on the source side, which can be fixed by a DBA
Thanks
