Created a Destination in SAP BTP for  S4 Public Cloud (API_BUSINESS_PARTNER - Service)  and destination connection works fine also added all required additional property(sap.applicationdevelopment....,sap.build.usage,sap.processauto...).

But When creating a action for the "Odata Destinations" its giving error saying "Service unavilable.Failed to fetch the Metadata.Unexpected token '<',<html><.." id not valid json.

Tried changing few things in destination but nothing works ( Like adding $formt=json,other additional properties ) but no luck.

Please suggest if im missing anything or whats the issue.

I suspect the authentication is not working well.
When its authentication fails, the S/4HANA backend system returns error messages with HTML format and that would be be parsed in the caller system.
And then, what you may need to check fist would be about the authentication settings.

Hello,

Do you also have an S4 Extensibility instance created for the respective Communication Arrangement?

Assuming this is an extension application built in SAP Build, as you have configured that parameter?

Please check this document. 

Hope this helps.

Thank you

Tiago Ribeiro

@TiagoRibeiroi am trying to create a action in BPA and when i do Odata destinations i get this error.

creating  S4 Extensibility instance  is mandatory when creating actions connecting to s4 public cloud?

Not doing any extensibility .wanted to create a BPA to read Business partner details and create a form and send for approval.

But the process to create the BP is started/triggered in the S4 correct? So you might want to implement an event to be capture by the SAP Build Process Automation tool to execute the conditions check. Or how will you trigger the API READ in S4? Is it S4 Public Cloud or OnPrem or Private?

@TiagoRibeiro S4 Public Cloud. Yes the trigger will be a API Event BP create in S4 Public cloud and on that trigger in BPA we get the BP ID and we use this action to read details of BP from S4 to validate some fields.

So the current issue you are facing is while receiving the event when the BP is created, meaning you don't receive the event, or when you execute the ODATA Read action to the BP communication arrangement in S4?

Hello @suneelrelish 

Can you also add the following parameters/properties in the destination pointing to S4 BP API? 

  • sap.processautomation.enabled = "true"
  • sap.applicationdevelopment.actions.enabled = "true"

I believe with these properties the connection should be successful. 

Please try and let me know. 

Thank you

Tiago Ribeiro
