User Logged IN data filtration in Paginated Report without relationship

Dear All,

I have a report published in Workspace, and am using the dataset to create a paginated report, the report has to many columns (thats a totally different challenge though).

What i want is, when this paginated report is published in a workspace and when a user logged in to see/print the report, he should only see data relevant to him. For this i need help with 2 question.

1. How do i filter data with logged in user

2. The main data doesn't contain user information, the link between main data and user data is two column having code information, residing in 2 different column (Code 1 & code 2), so how does i link this, and satisfy the condition with both parameters.

Dataset 1 - Main data (includes code 1 & code 2 column)

Dataset 2 - User data (contains UserID and code 1/ code2 column)

Dataset 1

Dataset 2

Thank you for any help!

Best Regards,
