Power Automate - List Rows with LookUp

Report

Posted on by alovalpwa

I'm working in a flow using Dataverse connector and List Rows action.

I have two tables Appoint and Client

In the table Appoint the column ClteId is a LookUp column pointing out to table Client (many-to-one).

In the "Select columns" option of List Rows action, I want to declare columns from table Appoint and columns from table Client.

I've wrote down a FetchXML query. If I do not include in the query a link-entity reference everything goes well.

But when I include in the query the link-entity sentence the List Rows action is trying to retrieve from the server in a loop.

Any idea of what is wrong?

Best regards

@alovalpwa ,

Please find below fetch xml query. Test 1 and test 2 are two entities. Test 2 has lookup of test 1. For below query, I am getting test 2 name from lookup.

<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
<entity name="cr5b9_test2">
<attribute name="cr5b9_test2id"/>
<attribute name="cr5b9_name"/>
<attribute name="createdon"/>
<order attribute="cr5b9_name" descending="false"/>
<link-entity name="cr5b9_test1" from="cr5b9_test1id" to="cr5b9_test1" visible="false" link-type="outer" alias="a_a08f4df0d2fceb1194ef6045bd72e732">
<attribute name="cr5b9_name"/>
</link-entity>
</entity>
</fetch>

As I mentioned earlier, try to formulate fetch xml from advanced find or fetch xml builder from xrmtoolbox.

If it answers your question, kindly give kudo and accept it as solution.

Regards,

Prakash

Hi @alovalpwa,

Couple of things I noticed:

Your FetchXml looks good apart that you're missing the alias property in the link-entity element. Add a friendly alias and then the results from the link entity will return in the format "aliasname.columnphysicalname"

You also applied a filter in the filter box. I don't think both are supported (I may be wrong). Apply the filtering directly in your FetchXml instead since you using FetchXml.

Hope this helps!

I still have the same issues, the list row action retries and get internal server error in a loop.
The filter expresion is "addHours(startOfDay(utcNow()),-2)".
How could I write it down in FetchXML query?

Yup if I understand the logic correctly you can use the last-x-days operator. Example:

<fetch> <entity name="account" > <filter> <condition attribute="createdon" operator="last-x-days" value="2" /> </filter> </entity> </fetch>

Note: all dates are already stored as UTC in Dataverse.

Also, your initial FetchXml was cleaner, you can omit all the properties in the <fetch> tag and remove the visible property from the link-entity tag.

Hope this helps!

You need to reference the property with an expression, example:

Expression format: items('apply for each name')?['alias.cltefirstn']

@EricRegnier
It was hard but I've got it.
And now my last question for this time.
My target is to create a text file separated by semicolons .
I don't see how to change that when I create the CSV table.
Any advice?
Thank you very much

Haven't fully tested but you can try Replace "," with ";" in a Compose action. Expression:

replace(body('Create_CSV_table'), ',', ';')
