Coule I select one to main basis

[lichang422]

I using Qlik Sense.

I have 2 tables And I make an association with table by L1Name.

Because one table have 3 kinds of data like ProductResult_History.

And the other one have 4 kinds of data like L1Signal_Pool_Active.

Can I show only  L1Name of ProductResult_History without L1Signal_Pool??

Thank you.
