Update an item where table has a dynamic value (only Row item available)

Posted on by darren1372

I have created a flow where a user can enter a table name or many table names separated by a semi colon.

The workflow splits the text in an apply to each, then users the table logical plural name in a list rows action.

In another apply to each - derived from the list row action - I have used an expression to grab the owner id value and set it to a variable called varOperationsOfficer, as I need this to update a field in the current item, and since the list action is using a dynamic value for the table ,the fields are not available in the dynamic content menu.

So I have:

I now need to update a field in the current table called OperationsOfficer with the value of the 'varOperationsOfficer' variable,

Normally in the action below (not using a dynamic value for a table) you would target the OperationsOfficer field (which is a lookup field to the user table) and update by:

OperationsOfficer: systemusers(varOperationsOfficer)

However, since I am using a dynamic value for the table in the action below I only have Row Item*

So my question is, how do I update the OperationsOfficer field with my variable?

Hi,

You will need to pass aa JSON as input for the Row Item. First, find the OperationsOfficer column logical name, and use it as key in the JSON. As value, you can use systemusers(varOperationOfficer).

To find the column logical name, go to the Dataverse table column and click Edit column. After expanding the Advanced options, you will see the logical name:

In Power Automate, your action will look like this

In my case, I'm updating a single-line text type column, but the same logic can be used for a Lookup one.

Let me know if it works for you or if you need any additional help!

Hi Rzaneti

thanks for your response but it is not working.

So far I've tried:

These returned there is an error in the payload by the user

This returned the error:

CRM do not support direct update of Entity Reference properties, Use Navigation properties instead."

CRM do not support direct update of Entity Reference properties, Use Navigation properties instead."

This ran successfully but didn't update the field....

If you get get it to work with a lookup field to the user table please let me know. At the moment it's not playing ball!

Hi @darren1372,

I ran some tests and it looks that I found a solution:

You need to use [schema_name]@data.bind as key. So far, we were using the logical name instead. It's tricky, because the schema name is usually the same of logical one, but with some characters in upper case (like "R" in Relateduser, in my case).

After this small change, the flow ran successfully:
