--First get the table name 
Source = Lakehouse.Contents([]),
#"Navigation 1" = Source{[workspaceId = "12333r3r"]}[Data],
#"Navigation 2" = #"Navigation 1"{[lakehouseId = "aaefefe"]}[Data],
my_table_name = #"Navigation 2"{[Id = "est", ItemKind = "Table"]}[Data],
 
---Then get the data from the table name above
#"Navigation 4" = Source{[workspaceId = "6d9a79dc-e9bc-42f8-958b-e5e896744437"]}[Data],
#"Navigation 5" = #"Navigation 1"{[lakehouseId = "aa6082ce-3048-4bc0-aa16-80e06a37697d"]}[Data],
#"Navigation 6" = #"Navigation 2"{[Id =my_table_name , ItemKind = "Table"]}[Data]

    Hi Winnie2024 

     

    Thanks for using Microsoft Fabric Community.

    Apologies for the inconvenience.

     

    If you get an Expression.Error: The key didn’t match any rows in the table in Power BI, it means that you’ve made some changes to your source file and haven’t updated them in the Power Query. 

    In most cases, the error arises when the Sheet’s Name is not the same on your original and destination file.

     

    For more details please refer : How to Fix “The Key Didn’t Match Any Rows in the Table”.

     

    I hope this information helps. Please do let us know if you have any further questions.

     

    Thanks.

    Could you please share the full query that you have for your "get table name" query? It should yield a single scalar value. Basically a text string. If it doesn't, that's what's causing the issue in the subsequent query.
