Embedded canvas app how to get the selected lookup field value guid?

(0) ShareShare

Posted on by shennu 702

The canvas app is embedded on a Case Entity form.

There is a 1:N lookup field called Port, the the parent entity of this relationship is Port.

With the preview version of embedded canvas app I can get the GUID of a the selected value of a 1:N lookup field I could use

First([@ModelDrivenFormIntegration].Data).tmit_portName

Since it has gone GA, it is said on the documentation that we should use the ModelDrivenFormIntegration.Item to access all data from the parent entity of the embedded canvas app.

So I use

[@ModelDrivenFormIntegration].Item.Port.Port

so Port is the unique identifier on the Port entity.

Sadly [@ModelDrivenFormIntegration].Item.Port.Port

or Text([@ModelDrivenFormIntegration].Item.Port.Port) always returns blank

Eventhough there is no error, and both Port appears in the powerapps intellisense

Any ideas?

    Hi,

     

    You need to be specific about which value you want to retrieve if the lookup is polymorphic.

     

    Following link explain in detail about the same.
