Logic Apps standard connecting to SAP on Azure

Sharmishtha Sarkar 36

Hi,
I need to connect to SAP on Azure from Logic Apps Standard
Logic Apps Standard VNet Integration with SAP VNET is enabled.

Do we need to use a OnPrem Data Gateway to connect to SAP from LA Standard ?

Do we have any documentation for Logic Apps standard connectivity with SAP ?

Regards,

Hi @MayankBargali-MSFT ,

Can you please confirm when we can expect SAP In-Built connector available in Logic Apps Standard ? Also, is there any plan to have extension available for SAP to create custom built-in connector ?

Thanks & Regards,
Kritika Singh

@Kritika Singh , the connector is already available as a Built-in connector in Preview with only one action, that is the ability to Send a message to SAP.

Hi @David GROSPELIER ,

Yes, but we also need other operations as well. For example, to receive IDOCS from SAP. Also, we don't know when this Preview will be GA to move the integration to PROD environment.

So for now till we have this SAP Built Connector as GA, we are using OPDG but there also we found the limitation with regards to data transfer.

Hi @MayankBargali-MSFT ,

We are using OPDG to connect to SAP systems. But the problem is limitation of OPDG. It supports only 2MB of data operations. Is there any alternative solution.

As of May 2023, the built-in SAP connector is available, doesn't use the OPDG, and is no longer limited to the 2 MB of data from the OPDG.

@Anonymous Only built-in connectors support to access resources on Private IPs on the VNET integration feature as they run alongside of the Logic App standard host runtime. Whereas Azure connectors (SAP in your case) run in a shared environment and they don’t support to access resources on Private IP addresses and resources must be accessible from the Internet or via OPDG if it’s in a private network.

Unfortunately, as we don’t have SAP as a built-in connector yet so you need to use OPDG to connect to SAP from your Logic App Standard environment. Connect to SAP systems from Azure Logic Apps document is still valid for the logic app standard environment. The product team is working on the feasibility but there is no ETA to be shared as of now. Once this feature will be in the preview we will update our document with more details.

We can still enable VNET integration while workflows have Azure connectors but are required to open traffic to Azure connector Ips on NSG or NVA/F/W on VNET integrated subnet along with target system on public IP.

As of May 2023, Logic App standard now has a built-in connector where you no longer need to use OPDG to connect to SAP. Instead, you can use the VNet integration.

Hello @David Burg - MSFT

I hope you are doing well. I'm currently working on a scenario using Azure Logic Apps that involves retrieving data from SAP whenever it gets updated and passing that data to LIMs, as well as vice versa. I have a couple of questions regarding this scenario.

Firstly, I'd like to confirm if it's possible to achieve this using standard Azure Logic Apps.

Secondly, for SAP integration, I'm wondering which trigger I should use. It seems that the built-in Register RFC server trigger is unable to receive calls from SAP when deployed on Azure. On the other hand, the managed trigger "when a message is received" is not a polling trigger. I specifically want the Logic App to be triggered when SAP BAPI objects or data are updated.

If I opt for the managed trigger, how can I implement the Logic App to be triggered when SAP updates occur? Do I need to implement the triggering of Logic Apps on SAP events at the SAP end?

Your assistance with these queries would be greatly appreciated. Thank you!"

I can't speak to the specific of 'LIMs', I don't recognize that acronym.

The built-in SAP trigger had a limitation to receive call from SAP when deployed to Azure in its Public Preview. This has since been resolved, the built-in SAP trigger is Generally Available and can be called from SAP when deployed to Azure.

Neither of the managed or built-in SAP triggers are polling triggers. The managed trigger for SAP is a webhook-based trigger, so you will see the webhook renewal calls every 5 minutes in the trigger history. Those are not polling calls, they are simply maintaining the RFC trigger registration state on the otherwise stateless OPDG.

The calling of an external RFC Server by SAP (or sending an IDoc) upon a given internal event of SAP is an ABAP configuration by the SAP engineering. This is not something Logic App engineering can advise upon. Please talk to your SAP ABAP engineering team.

Please use the new and generally available built-in connector for SAP. See https://techcommunity.microsoft.com/t5/azure-integration-services-blog/using-logic-app-standard-to-connect-to-sap/ba-p/3737354 and https://learn.microsoft.com/en-us/azure/logic-apps/logic-apps-using-sap-connector?tabs=standard
