You’re referencing a naked table[column], that is not allowed.
What is your objective, can the Complaint[Initiator] return a scalar value since you have a M2M relationship? Please share a sample PBIX so members can better assist you. Thanks!
@Melissa Complaint[Initiator] and ComplaintId[Supporter] is what i am referencing, they are two different tables and they contains Names which is text.
What i am trying to achieve is that, when i click Initiator Tab, it should only show me all the names of Initiators as Filters in a Table when i have created already and vice versa when i click Supporter. So, i should be able to switch between Initiator and Supporter
Okay so SWITCH can only return a scalar value so that’s not an option in your scenario.
Instead I would suggest you look into: Buttons, Actions and Bookmarks. You can find a short video in the topic below but this technique is very versatile.
Just a quick note, when using Buttons in Power BI Desktop you have to hold down CTRL + Click (however that is not required in the Service).
