Accessing Dynamics 365 Intersect Tables

[MattTaylor]

Hi folks,

I'm wondering if someone can help with a problem I'm having. I'm trying to access a Dynamics 365 CE intersect table (N:N relationship). I've used the guide here: https://www.sikich.com/insight/how-to-find-n-n-relationships-with-dynamics-365-logic-apps-and-flow/ but unfortunately it's not working and I'm getting an error when I run/test the Flow. The error is BadGateway and looks like this: 

{
  "error": {
    "code": 502,
    "source": "europe-002.azure-apim.net",
    "clientRequestId": "9e06f5e0-546a-4001-9343-be3e137a7860",
    "message": "BadGateway",
    "innerError": {
      "status": 502,
      "message": "Dynamics 365 system returned invalid entity metadata.",
      "source": "commondataservice-we.azconn-we.p.azurewebsites.net",
      "debugInfo": "clientRequestId: 9e06f5e0-546a-4001-9343-be3e137a7860"
    }
  }
}

If I use the API URL then it doesn't return an error with the name of the table - <relationshipname>set

Any ideas?

Thanks in advance,

Matt

Hi @MattTaylor ,

Could you please share a screenshot of the configuration of your flow?

Hi Alice,

Thanks for getting back to me, here's what I have: 

This is using the Dynamics connector but I've tried with the CDS one as well. 

Kind regards,

Matt

Hi Alice,

We really need to be able to do this, could you confirm that accessing intersect tables should be possible and if so link me to instructions?

Kind regards,

Matt

Hi Matt,

Not sure why you are getting 'Bad Gateway' error, I am able to access the intersect entity using '<relationshipname>set'. Do you want to try using just 'List Records' action and see if you are still getting the same error. 

Though, I still have to figure out a way to update intersect entity using Flow.

Thanks,

Mohit

Hi Mohit,

What's weird is that I was able to do this before on another environment but I just can't get it working now - I'll have another go with the 'list records' action but I'm pretty sure I already tried that. 

When I was testing before (using a canvas app) I couldn't find a way to update the intersect table, I don't believe it's possible at the moment. For that system I had to then use a custom N:N table. 

Cheers,

Matt
