Filter on a column added by an $expand query

I am querying Dynamics 365 (Project Service Automation PSA) data using the Dataverse List Rows action.

I want to return the rows for a particular user but I want to add an additonal clause to bring back only those rows where the projectTask = "Vacation". Unfortunately, projectTask is not on that table, so I have to expand the Project Task table. However, I can't work out a way of then filtering on that new field. My thoughts:

1. Do I try to add it to the filter, referencing the newly added column? Seems to fail.

2. Do I try to add the filter to the expand clause? I couldn't work out the syntax.

3. Do I just add the column in this particular step and then try to filter the entire table in a subsequent step? If so, can anyone advise what would that Action step I could use?

Hoping someone can help!

Hi @ghdunn,

Maybe you can use the fetch xml query instead?

In that field you should also be able to add filters for linked entities:

Hi @ghdunn,

You can use the Filter query to filter by a lookup's properties.

For example, if I want to get all Accounts where the Primary contact's Gender is Male, my filter query would look like the following:

(primarycontactid/gendercode eq 1)

Thanks @Expiscornovus Sorry for delay but on your recommendation have spent some time digging into FetchXML and you are right...it seems a good way to do this...especially since you can design the FetchXML query in Dynamics Advanced Find and cut and paste the FetchXML. However, one more question if I may. Do you know if I can use a combination of the two? If I bring a column back in Fetch XML, can I then refer to it in the Filter field? The reason I ask is that adding a dynamic content element to FetchXML field is quite fiddly. The example below fails with the error: "Could not find a property named 'businesstypecode' on type 'Microsoft.Dynamics.CRM.contact'." This makes some sense but I wonder if there is a way around it?

I realize this is quite an old post, but I think Chris' answer more directly solves this issue. FetchXML is certainly an option, but the '/' syntax for nested odata filtering is slick.

Hi @ChrisPiasecki I recognize this is old, but this is useful! In Dataverse Query, I brought in my wanted Child column using Expanded Query:
outputfromlookupcolumnNavigation($select = modifiedon). This works, but how do I filter on the child modifiedon?

I placed this in the Filter rows with no luck: outputfromlookupcolumnNavigation/modifiedon

Any thoughts or suggestions?
