Relationship and Slicers

[rohanjha1988]

Hi All,

I have an issue in understanding a fundamental of relationship. 

I have a table called - FrontlineVisit. In this table I have day wise visit details of my frontline sales team to different clients. In this table some of the columns are - Name, Emp Id, ClientID, VisitDate,VisitTime,VisitDay,ClientTypeName(Retail,Wholesale,ModrenTrade), ClientType Id etc. 

I have another table - ClientType. This is basically a dimTable in which I have 2 columns - ClientTypeId, ClientTYpeName

Now these 2 tables are not linked with each other. 

I have a measure called - #Visit which basically is a Count fuction telling me the no of visits. 

I made a visual - Name and #Visits. Both these are taken from FrontlineVisit table itself. Now if I apply a slicer of ClientTypeName from ClientType table, this slicer works on the visual. 

When these tables are not linked with each other then how can a slicer from a non related table works on a visual?

@rohanjha1988 what you're describing definitely doesn't sound like the expected behavior.

I'm assuming you've already verified this, but the first thing I would double-check is that the ClientTypeName column being used in your slicer is in fact the one from ClientType table, not from FrontlineVisit. 

The next thing I would verify is that the #Visit measure is indeed counting a column from FrontlineVisit, and not mistakenly one from ClientType.

The third thing I would check again is that Power BI has not "automatically detected" and created a relationship between the tables for you on the ClientTypeName column, unbeknownst to you.  This can sometimes happen when a column with same name exists in multiple tables.

Actually its the 3rd option. The moment i applied the slicer, it automatically detected the slicer.
