Hi @vishalgoyal2472 ,

 

You can set below formula in the DefaultSelectedItems property of the combo box inside the data card:

{
        Id: LookUp('List B', Title = "test", ID), /* <- I assume that the Title is the source column and it is a Single line text type column in your 'List B'*/
        Value: "test"
    }

Note: Please add your 'List B' as a data source within your app firstly.

 

More details about setting a default value for a LookUp field in PowerApps, please check the following thread:

Please also check and see if the following blog would help in your scenario:

In this way, you only need to change the property of DefaultSelectedItems of the combo box, and you can leave the default settings for Items and Update property inside Form.

If I select multiple value in Combo box , Lookup function will work?, eg.. I selected a, b , c , , Out put could be in text box (Angel, Bangle,Chamber )
