Allow end-users to input an unmasked User ID to filter model built with masked User ID

[hamachekm]

I have a Power BI model that is built using a masked User ID ("12ABC"), due to data privacy concerns.  

End users would like to be able to input the original unmasked User ID (think of Social Security Number or Tax ID number)  ("123456789") and be able to filter the model. 

Currently, we have a separate Excel model with VBA code for a custom hash function that allows this one-way look up to happen. I would like to put this all in Power BI, so there is no more Excel to use. 

I do not want an end user to be able to view all the unmasked User IDs. The user can input unmasked User ID and see if there is a match. I just do not want to allow a reverse lookup, where a user inputs all the masked User ID and then finds out the unmasked User ID.

Can you think of a way that this can be done?

Thanks,

Mike

Hi Polly - Thanks for checking, but I must say that your reply was not that helpful. I know that VBA is not in Power BI. I was explaining what I was doing in Excel as a way to help provide more information for solving this problem. 

I do think I have a solution here, and will post what I do when I have a chance.

Hi @hamachekm ,

Power BI Desktop is an entirely separate application from Excel and it has no VBA interface currently. Someone has submitted this feature request here: VBA for Power BI Desktop You can click to vote it up.

If one the Service, you can use rls.Row-level security (RLS) with Power BI - Power BI | Microsoft Learn
