Dynamic filtering URL issue

Hi krzysztof ,

The issue is with the URL structure. When adding extra parameters like filter=, you should use & to connect them, not another ?.

1. There should be only one ? after /reportid.
2. Additional parameters should be added using &, like &filter=....

If you want to create dynamic links for different EANs in Power BI, use a DAX measure. Display the links in a table visual and format them as Web URLs for easy access and clicks.

FYI:

For more details, here the official Microsoft documentation you can refer
