SAP Service and Asset Manager (SSAM) Mobile Application integrates with SAP Field Service Management (FSM) as part of Field Service Technician persona using Proaxia connector. SAP SAM is now integrated with SAP FSM planning board and show the current status of orders and tracks technician’s location to facilitate scheduling and dispatching. As part of this Integration, SAP SAM also supports FSM Smartforms and allows the SAM mobile application to download, modify and upload FSM Smartforms assigned to an activity/operation.


Process flow for SAP SAM Integration with SAP FSM


SAP SAM integrated directly with SAP FSM using the Service and Data APIs provided by SAP FSM. However, the underlying objects that need to be updated, (e.g. Service Orders (Service Calls in FSM), Operations (Activities in FSM), Employees (Persons in FSM) are created by the Proaxia connector. Therefore, the following pre-requisites must be implemented for the end-to-end scenarios to work.

Prerequisites:




To execute the supported integration scenarios between SSAM and SAP FSM, the following prerequisites must be met and assuming that the Proaxia FSM connector will be configured and set up to replicate the data between the SAP backend and SAP FSM system.



  1. Proaxia FSM connector is configured and set-up to replicate data b/w SAP & FSM system

  2. Enable 'External Id' flag under FSM connector Company definition section.

  3. Implement BAdi methods to provide ID mapping between SAM & FSM.


Implementation Details:


The following sections will explain the details on how to implement these prerequisites.

Make sure Proaxia FSM connector is configured and set-up in your environment to replicate data b/w SAP & FSM system. For more details about Proaxia connector, refer to the following documentation:

Enable 'External Id' flag under FSM connector Company definition settings


From SAP backend system, use menu option of FSM Connector, Customizing --> Objects --> Company --> Company Definition (Transaction Code: /PACG/ECM_COMP).


FSM Connector Company Definition


By enabling the External Id flag, you can switch on sending the External Id from the FSM connector to FSM.


Enable External Id from FSM Connector settings



Implement BAdi methods to provide ID mapping between SSAM & FSM:


Mobile Application Integration Framework (MAIF), which supports SAM backend integration features, provides different BAdi options to determine cross-referencing of key fields between FSM Connector and FSM Cloud system. The Badi /MERP/CA_FSM_CROSSREF_BADI is delivered for both ERP & S/4HANA system to support this feature with following interface methods.


BAdi Interface for FSM Id mapping


The following code samples are an example, you may need to make additional adjustments for your environment.

  1. Add local method GET_COMPID to determine the FSM company Id. This method required for the GET_EMPLOYEE_IDS BADI method in Step2. This method returns the following data:

    Import Parameter:  iv_account TYPE /pacg/ecm_cloudaccount.              Return Parameter: rv_compid TYPE /pacg/ecm_compid.

    METHOD get_compid. 

    DATA: lv_string1 TYPE string,
    lv_string2 TYPE string,
    lv_account TYPE string,
    lv_fsmaccount TYPE /pacg/ecm_cloudaccount,
    lv_fsmcompany TYPE /pacg/ecm_cloudid,
    lv_compid TYPE /pacg/ecm_compid,
    ls_cacc TYPE /pacg/ecm_cacc.

    lv_account = iv_account.

    SPLIT lv_account AT '&account=' INTO lv_string1 lv_string2.
    SPLIT lv_string2 AT '&company=' INTO lv_string1 lv_string2.

    lv_fsmaccount = lv_string1.
    lv_fsmcompany = lv_string2.


    ls_cacc = /pacg/ecm_cl_d_access=>get_cloudcomp_definition(

    iv_cloudaccount = lv_fsmaccount
    iv_cloudid = lv_fsmcompany ).

    rv_compid = ls_cacc-compid.

    ENDMETHOD.​


  2. Implement BAdi method /MERP/IF_CA_FSM_CROSSREF_BADI~GET_EMPLOYEE_IDS:

    This method is a prerequisite for saving geolocations captured from SAP SAM to the SAP FSM planning and scheduling board.The method must return the FSM internal Employee ID(s) (Field id of the Field Service Management Person entity) based on the personnel number(s) provided.Use the importing parameter IO_ACI_SERVICE to execute a service call to Field Service Management for retrieving the id based on the code in the following code example.



    NOTE: The assumption is that the ExternalId field for the ‘Person’ entity in FSM is populated with the internal format of the Personnel number in SAP. If this is not the case, then the lv_cloud_name may need to be used to query the ExternalId.


    This method returns the following data:






    • ET_OBLNK: Object link table that has the unique Object IDs in Field Service Management for all the Personnel numbers specified in IT_PERNR with the following fields populated:





      • OBJECT_KEY: Personnel number in the back end (LOW property in the range table)




      • EXT_OBJECT_KEY: Object Id of the Employee/Person in Field Service Management.



        METHOD /merp/if_ca_fsm_crossref_badi~get_employee_ids.

  4. Implement the method /MERP/IF_CA_FSM_CROSSREF_BADI~GET_SERV_ASSIGN_ID:

    ).
    ENDMETHOD.​


  5. Implement the method /MERP/IF_CA_FSM_CROSSREF_BADI~GET~GET_SERV_ASSIGN_STATUS_ID:

    This method is a prerequisite for implementing relevant status updates from SAP SAM to the SAP FSM planning and scheduling board. Use the QUERY_FSM_SERVICEASSIGNSTATUS method from the /MERP/CL_CA_FSM_INTEGRATION class to get this value based on the following code example.



    METHOD /merp/if_ca_fsm_crossref_badi~get_serv_assign_status_id.

    es_oblnk = es_oblnk
    ).
    ENDMETHOD.​



Known Issues:


During initial sync in SAP Service & Asset Manager 2210 application, no FSM Smartforms are downloaded onto the mobile client. This is because while downloading the FSM Smartforms Instance the associated activity IDs mapping can not be found. Following SAP Notes will fix these issues:

3308616 - FSM Smartform Instances cannot find associated activity ID - SAP ONE Support Launchpad

3311163 - All controls in an FSM Smart Form are read-only in SAP Service & Asset Manager

3312313 - Changes to FSM Smart Forms on mobile don't get reflected on FSM Planning Board UI

Summary:




With the Integration Scenario explained above, SAP Service and Asset Manager (SSAM) can now be able to integrate with SAP Field Service Management (FSM). SSAM integrates directly with SAP FSM via MAIF from backend using the Service and Data APIs provided by SAP FSM. However, the underlying objects that need to be updated, (e.g. Service Orders (Service Calls in FSM), Operations (Activities in FSM), Employees (Persons in FSM) etc., are replicated by the Proaxia connector. To support this direct integration from SAP SAM to SAP FSM, we provided dedicated BAdi options to ID mapping, to determine the cross-referencing of key fields between the FSM connector and FSM.
