[BTP] Create sap-successfactors-extensibility service providing a technicalUser

Prerequisite, you have registered an SAP SuccessFactors system in your Global Account (see here). Creating the sap-successfactors-extensibility service can be done via command line:

#Created the service instance
#An HTTP destination on a subaccount level with the same name as the service instance name is automatically generated
cf create-service sap-successfactors-extensibility api-access myInstanceName -c '{"systemName": "SFCPART000000","technicalUser": "sfadmin"}'

#Bind the instance to an application
cf bind-service myApp-srv myInstanceName 

Find an explanation of the parameters here: https://help.sap.com/docs/btp/sap-business-technology-platform/authentication-type-json-file

This service instance will result in creating:

  • a separate OAuth2 client application on SFSF side (can find in SF in Manage OAuth2 Client Applications)
  • a separate destination definition on a BTP sub-account level

The technicalUser parameter can be specified only during creation. There is no possibility to provide it afterwards using cf update-service. It may be possible to manually update the technicalUser in the destination, which got automatically created. But I did not test this yet.

Of course, the same service creation can also be done via mta.yaml.

 #####################################################################################################################
  # SuccessFactors Extensibility Service
  #####################################################################################################################
  - name: myInstanceName 
    type: org.cloudfoundry.managed-service
    #type: org.cloudfoundry.existing-service
    parameters:
      service: sap-successfactors-extensibility
      service-plan: api-access
      config:
        systemName: SFCPART000000 # <-- Provide your system name
        technicalUser: sfadmin

For initial deployment, you need the line type: org.cloudfoundry.managed-service. For all further deployments, you have to comment that line out and comment in the next line type: org.cloudfoundry.existing-service. Else you will receive an error.

This report can be handy, especially since S/4HANA 2023 seems to have restricted the “classic” import way by using TCode CG3Y and CG3Z. See note 1949906, where it is recommended to create a custom report.

[CAP] Download MTA deployment logs after deployment

With this simple command, you can download the MTA deployment logs of your recent deployment. Instead of manually having to use cf dmol -i <operation id>, just save the command (replace appId with your Id) as a shell script, make it executable (chmod +x) and run the script after your deployment. It stores the recent logs into the folder logs.

dmol is short for download-mta-op-logs

cf download-mta-op-logs --mta <appId> --last 1 -d logs  

To just have a quick look at the recent logs, use

cf logs <appId>-srv --recent

[CAP] Check if User exists in SuccessFactors

To check if a record exists, you can simply use the HEAD query.

“HEAD is almost identical to GET, but without the response body.” (https://www.w3schools.com/tags/ref_httpmethods.asp)

Unfortunately, there is no shortcut in CAP for a HEAD query, so simply use send with method HEAD.

    sfsfSrv = await cds.connect.to('sfsf')

    try {
        await sfsfSrv.send('HEAD', `/User('${userId}')`)
        return true  // status 200
    } catch (err) {
        return false // status 404
    }

Quick way to open a PDFViewer in your UI5 App:

			pdfViewer.setTitle("My PDFViewer Title") // title of the popup, not the viewer
