Direct Query - New Table with some Values from a Direct Query Table

[NewPBIe]

Hello everybody, 

I need to work on a direct query dataset and for some advanced filtering I need to split a String Value in more Substrings, each to be assigned to a separate column. I tried with a SWITCH + CONTAINS Query but I received Error Message "The expression specified in the query is not a valid table expression.".

Is possible to generate a table from values in a direct query?

Thank you in advance!

Hi @NewPBIe ,

If I understand correctly, you are trying to get a column which include special charactes of strings by creating a calculated table. Am I right? According to the error message, it caused by using scalar function to create a calculated table. What's the formula of your calculated table?

You can refer the following official documentation to create a calculated table:

If the above ones can't help you get the expected result, please provide some raw(fake) data in your direct query table (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It would be helpful to find out the solution. You can refer the following link to share the required info:
