Change Data Source Dynamically Based on user selection in Slicer

[ArshadMagdum]

I am tasked with a Power BI project involving a SharePoint application that organizes projects, each with its respective subsite. My objective is to access the 'Monthly Budget' list, which shares the same name and columns across all subsites, within Power BI based on user selection through a slicer.

Presently, I retrieve data from a specific subsite using the URL 'http://abc2019/pwa/Project1/_vti_bin/listdata.svc.' Yet, I require the capability to dynamically alter the 'Project1' value based on user selection from the slicer. For instance, if the user chooses 'Project2' within the Power BI slicer, the visuals should populate data from the 'Monthly Budget' list located in the subsite of 'Project2'.

it has nothing to do with reportserver,

anyway: to achieve this, you have to load all (at least all of the user selection options) lists from sharepoint and add a "list" or "source" column to your fact table (which then should contain ALL lists) which is connected to your slicer. then you can slice.

SharePoint Lists are Import Mode data sources, so your requirement cannot be fulfilled.
