Connect to NAV 2017 or NAV 2018 on-premises

Hi Guys

For the first time I need to connect to an on-premises instance of NAV 2017 or NAV 2018. I have configured the On-Premises Data Gateway, which seems to be running fine.

Now in Powerautomate Flow when I select a NAV Connector action to create record I see following parameters. Now since the NAV Instance is running on-premises I need to tell the connector to rout the request over the On-Premises Gateway which is running and available in power platform. How can this be done?

Regards

Hello @Symira ,

You need to download & install On-Premise gateway first in your local computer network and than need to setup gateway on Power Automate. Once you do that you will be able to connect your On-Premise NAV with Power Automate. Detail information is on below link.

https://docs.microsoft.com/en-us/power-automate/gateway-reference

Re: Connect to NAV 2017 or NAV 2018 on-premises

Hi Anupam
Thank you for your reply. In fact the On-Premises GW is already installed and also configured in Power Automate. What I don't understand is how to tell the connector to route the connection url (Odata feed url) over the Gateway (please ref. the snapshot above). In the snapshot I don't see any field where I can tell the connector to do so. Am I missing some point?

Tnx

Hi @anupam8555

Just an update.
As you can see in the first screenshot the Gateway is Online
When I try to connect to NAV using the Odata Url I get following error, which is understandable to me, as I don't see any option to tell the connector to resolve the URL by routing it over the Gateway.

Any idea?

Hi @Symira ,

Can you make sure you are using correct ODATA URL ? As per my knowledge OData URL for NAV2017 or 2018 could be :

If multitenant, it’s this format: http://mytenant.myservice.com:7048/DynamicsNAV/ODataV4/Company(‘CRONUS-International-Ltd.’)
If not multitenant, it’s this format: http://myserver:7048/DynamicsNAV110/ODataV4/Company(”CRONUS-International-Ltd.’)

Let me know if it works.

Thanks
Anupam

Hi @anupam8555
This didn't work either. In fact the URL I am using is the one displayed on NAV "Web Services" page. It works fine when I invoke the URL in a browser on the server itself. What is troubling me is the fact, that while configuring the connector there is no way to tell the connector to route the request through the on-premises gateway to resolve the URL. How in the world is it supposed to know where that "myserver" part of the URL is? Eg. while configuring a custom connector you can explicitly configure the connector to route via an "on-premises gateway".

Thanks.

Hello @Symira,

As this thread is a bit older, I don't know if you're still interested in an answer - here is one anyway 😉
It's my understanding the Dynamics NAV connector on the Power Platform is using independent of the gateway. In fact, there seems to be no way to get the connector to use the on-premises data gateway.
Instead, if you have configured NAV (and your firewall) correctly, you should be able to connect through the OData V4 endpoint using the link you referenced earlier.
The on-premises data gateway would only help you create a connection to the SQL database directly.

Hi @joe_hannes_col

Thank you for your feedback. Indeed, I am now considering exposing the NAV service to DMZ so it can be accessed from the Flow. I am though not very happy with the solution. The sole purpose of the On-Premises Data Gateway is to connect on-premise resources to the Azure tenant, which it does very well. It is only this NAV Connector which has become obsolete, or lacks the feature to route the traffic over the On-Premises Data Gateway that is already available in that tenant.

Regarding your comment that the On-Premises Data Gateway can only access SQL database. I think this comment is wrong. It exposes many more ressources than only SQL database. Please refer this link: https://docs.microsoft.com/en-us/powerapps/maker/data-platform/using-dataflows-with-on-premises-data

Hello @Symira,

Thanks for your reply. I agree, connecting to OData correctly is not the best solution, especially from a security perspective. But if we want to use the NAV connector, it is the only way as far as I know.
And you are correct, of course: I meant to say that in an NAV context, the on-prem data gateway can only be used to connect to the database directly.

Hi @joe_hannes_col ,

Another possible solution for this can be using a custom connector for the Navision On-Premise .

Depending on the SOAP/OData REST service provided by Navision You can create the custom connector
While creating the custom connector , select connect via On-Premise Data Gateway .
