Expand Record field using OData query

[LPenatti]

Hi everyone,

I'm building a report that uses OData as the data source.

As this data source has a lot of information, I'm creating a filter directly in the query, using $select=id,change
However, the change column is a Record type column, and has a bunch of fields inside it. I want to extract only the operatorId column inside the change Record. How to do this directly via OData query?

I've researched in different forums and everything I found and tested didn't work.

The problem is my lack of knowledge in that language.

This is the best documentation I could find but even it did not help me to do what I need:

http://docs.oasis-open.org/odata/odata/v4.01/cs01/part2-url-conventions/odata-v4.01-cs01-part2-url-c...

This is what I've tried so far:
$select=id,change&$expand=change($select=operatorId)

$select=id&$expand=change($select=operatorId)

$select=id,change&$expand=change/operatorId

$select=id,change/operatorId

Hi @v-shex-msft,

Thanks for your reply on my question.

I found a workaround for my problem using this content from Microsoft: 

Optimize Power Query when expanding table columns

Hi @LPenatti,

It seems like they do not allow you to nest multiple level URL conversion queries.

I'd like to suggest you only apply one level expand in these formulas, then you can use power query expressions to continue the following operations.
