How to send iOS push notification from ABAP to SCP Mobile Services

You wonder how to send push notifications from your SAP Business Suite system directly to your mobile devices.

Prerequistes:

Development access to a NetWeaver / Business Suites system

ABAP Git installed on your backend system

SAP Cloud Connector configured with principal propagation

An SCP sub-account with mobile services activated (Neo or Cloud Foundry)

A native app configured in mobile services with the push notification feature enabled

 

The goal is to be able to sent push notifications from your backend in ABAP directly to your mobile devices (iOS, Android).

Configuration Steps:

Step 1 – Create and configure an RFC destination

Step 2 – Import SCP certificate to the SAP System Trust Store

Step 3 – Test your connection

Step 4 – Install abapGit

Step 5 – Import the SCPmsPushNotificationREST_API repo in your system

Step 6 – Configure mobile services

Step 7 – Use the API to send push notifications

Step 8 – Configure your other systems

 

You can find the detail of all these steps on my GitHub repo that you will need to clone via abapGit

 

Activate the push notification capability of your iOS application in Xcode. You app should be configured with the SCP iOS SDK.

 

Launch / onboard your app and verify the device token has been uploaded successfully to CPms under user registration, check for the field APNS device token.

 

Create an ABAP program with your business logic for dispatching push notification to your devices, here is an example of how to used the API.

 

    DATA(notification) = zcl_scpms_notification=>create_apns_notification( ).

    notification->set_title( alert_title ).

    notification->set_body( alert_body ).

    notification->set_badge( badge_value ).

  DATA scp_users TYPE zscpms_user_t.

  TRY.
      DATA(push) = zcl_scpms_push_notification=>get_instance( ).

      APPEND INITIAL LINE TO scp_users ASSIGNING FIELD-SYMBOL(<scp_user>).
      <scp_user>-name = 'myUserID'.

      DATA(response) = push->push_to_app_users(
        application_id = application_id
        users               = scp_users
        notification     = notification ).

        response->get_status(
          IMPORTING
            code    = DATA(code)
            reason = DATA(reason) ).

        IF code BETWEEN 200 AND 299.
          "Success  
        ELSE.
          "Handle network error  
        ENDIF.

    CATCH zcx_scpms_push_notification INTO DATA(ex).
      "Handle exception error
  ENDTRY.

happy coding

  • Hi Alex,

    first of all thanks for implementing this class and making it available via GitHub. I’ve started using it and have to say that it really is super easy to use it.

    I have one question: you offer as well the content-available property. Can you share an example of how to use the classes to trigger a silent background push message? Is it enough to only set the content-available field to X, provide users and app id and don’t provide any other fields, e.g. title or body? Do you have any experience on this?

    Thanks,
    Alex

    • Hi Alex, glad to ear that,

      as for your background push question, yes it is a simple as setting the content available to X

      you should not supply any other fields (title, body) or they will be ignored

      add the device capability named background mode and check push notification

      also there are some different delegate API to hook up in your app delegate

      thanks

      • Hi Alex,

        thanks for coming back and provide an answer. Indeed, I figured out as well that I should only send an X in content available and keep initial all other fields.

        Checking in my app I could consume the silent push only if the app was in foreground. When my app was in background it seemed that nothing happened, I assume that I have to use some specific API offered by the SDK that would allow a more expansive operation (network requests to sync the offline store) as otherwise iOS will not allow me to do this.

        Would appreciate if you would have any details or could point me to an example on how to do it. Obviously would be very nice to have such an example in your GitHub repo. I will definitly contribute to this repo if there is any additional thing that I have and that might help others, thanks again for sharing your code.

        Thanks,
        Alex

        • from a server side perspective, there is nothing else to do

          if you want to support background notification, you need to add the device capabilities in Xcode for background modes and check notification …

          take in mind that if you force kill your app (close it with the app switcher), iOS will not wake your app when a background notification is sent … background notification works best when you app is minimized …

          also if you are running you app from Xcode then make sure you are using the APNS development in Mobile Services, check the log in MobileServices and you will know if scpms was able to forward the notification successfully to APNS

          if my memory is good, you have something like 30-45 sec to send a request to refresh your data

          add this method to your app delegate

          application(_:didReceiveRemoteNotification:fetchCompletionHandler:)

          you can find good articles/blogs on RayWenderlich

          hope that help
