UI5 Approval - Missing OData Service TASKPROCESSING

Hi Experts!

We are implementing SAPUI5 HR renewal Services with NW 7.4 and EHP7.

When we execute the approval applicaton, we are facing the following error message:

The error log shows that the TASKPROCESSING Service is missing:

I've checked already the following help-document:

We activated all the business functions. But indeed, the oData Service /IWPGW/TASKPROCESSING is missing (or at least not activated yet).

When I try to add this Service via /IWFND/MAINT_SERVICE, there is no search result:

How can we add / activate this service?

Thanks in advance!

    Please advise if you are using this on portal or NWBC?

    Looks of it you are using the portal, did you assign the correct portal and backend UI5 role?

    did you check the ping to the BPM webservice ? does it work?

    * note 1859438 Launchpad service generates relative URLs

    * note 1864001 Resolving of system alias for launchpad service

                   (Help for error analysis)

    * note 1875366 resolution of sm59 destinations in UI2-RunTime

    Follow these steps:

    Run Transaction SPRO

    Run activity  Manage SAP System Aliases  under ODATA channel

    Change system alias software version to /IWPGW/BWF

    Now the service should run ,

    Check in transaction /iwfnd/gw_client

    Do GET on url -  /sap/opu/odata/IWPGW/TASKPROCESSING/TaskCollection

    The previous error should be gone

    then send me the response and error log if exist.

    If you see in this transaction a good response, then most likely the
    server is configured and you can continue with the rest of the

    Steps are

    To use the Tasks by Draft, Tasks by Priority, and Tasks by Time lanes, make the following settings:

    • Activate the required OData services and configure the ICF nodes in your SAP NetWeaver Gateway system.
        For more information, see SAP Library for SAP ERP under
      SAP ERP Central Component -> Human Resources -> Personnel Management (PA) -> Personnel & Organization -> Landing Page -> Configuring the Landing Page -> Activating SAP Gateway OData Services, Configuring ICF Nodes, and Configuring the Task Gateway Service for Task Lanes.
        The information on the required OData services and ICF nodes is also available in the Administrator's Guide for HR renewal <applicable release> or in the SAP ERP Installation Guide <applicable release>.

      Please have a look at:  If you have an SAP NetWeaver 7.40 installation and you have previously created services for the Generic Channel that are still in use, you must install the software component IW_FNDGC 100. You only need to install this optional component if you have existing Generic Channel services.

      I am getting the same error as one of the members reported here. Have been checking all steps and see everything in place but still see the error. Any help is much appreciated.

      • Hi Naveen,

        Please look at the Maximilian's initial post and the 2nd post. You should look at the /IWFND/MAINT_SERVICE and the log.

        If your issue is different from "Missing TASKPROCESSING service", you should create your own discussion.
