IP address mapping and privacy levels

Hi All

 

I've been trying to map some IP address and have run a test following this advice which works fine however when I try to apply it to my main data I get this error "Formula.Firewall: Query 'New Students' (step 'Invoked Custom Function') is accessing data sources that have privacy levels which cannot be used together. Please rebuild this data combination." which I asume is because my main data source for the IP addresses has a Privacy Level of "private. Is there a way round this, or guidance on which privacy levels can be combined and the implications of doing so?

I am struggling with this exact situation you described in your prompt. I read through the article from the solution comment, but am unable to implement it. Is there any way you could share an example of how you solved this?

Thank you!!
