Query on Service Order Assignment Type in CRM Service Manager

Question

Hi All,
This query is regarding the Service Order Assignment type in CRM Service Manager.
While fetching the service orders from SAP, the ServiceOrderFetchBAPI calls the ServiceOrderAssignmentTypeDelegateFactory class
ServiceOrderAssignmentTypeDelegateFactory class contains {
1.  public static String ASSIGNMENT_TYPE_GLOBAL = "ServiceOrder.AssignmentType";
      public static String SECTION = "APPLICATION_CONFIG";
Question 1: Please explain about both the String values, Are these two values being fetched from the sap config panel ? If yes then please elaborate where can I check their respective values in SAP.
2. The method getAssignmentTypeDelegate compares each values and returns the respective assignmentTypes
public static ServiceOrderAssignmentTypeDelegate getAssignmentTypeDelegate(User user, SAPObject sapObject, BAPI bapi)
    throws Exception
    String assigmentType = user.getPropertyValue(SECTION, ASSIGNMENT_TYPE_GLOBAL);
    if (assigmentType.equalsIgnoreCase("1"))
      ServiceOrderAssignmentTypeDelegate assignmentTypeBAPI = new ServiceOrderByResourcePlanning(user, sapObject, bapi);
      return assignmentTypeBAPI;
    if (assigmentType.equalsIgnoreCase("2"))
      ServiceOrderAssignmentTypeDelegate assignmentTypeBAPI = new ServiceOrderByPartnerResponsible(user, sapObject, bapi);
      return assignmentTypeBAPI;
    if (assigmentType.equalsIgnoreCase("3"))
      ServiceOrderAssignmentTypeDelegate assignmentTypeBAPI = new ServiceOrderByMultiResourceScheduling(user, sapObject, bapi);
      return assignmentTypeBAPI;
    if (assigmentType.equalsIgnoreCase("4"))
      ServiceOrderAssignmentTypeDelegate assignmentTypeBAPI = new ServiceOrderByAccount(user, sapObject, bapi);
      return assignmentTypeBAPI;
Based on the values a new class is instantiated and it mentions their filter range to be set in BAPI
For ServiceOrderByResourcePlanning  -
public void setParameters(SAPObject obj)
    throws Exception
    String partnerGUID = this._serviceOrderComponentManager.getPartnerGUID();
    this._bapi.setFilterRange("IT_LRP_RESOURCE_GUID_RA", "I", "EQ", partnerGUID, "");
For ServiceOrderByPartnerResponsible -
public void setParameters(SAPObject obj)
    throws Exception
    String partnerGUID = this._serviceOrderComponentManager.getPartnerGUID();
    this._bapi.setFilterRange("IT_PARTNER_GUID_RA", "I", "EQ", partnerGUID, "");
For ServiceOrderByMultiResourceScheduling -
public void setParameters(SAPObject obj)
    throws Exception
    String partnerGUID = this._serviceOrderComponentManager.getPartnerGUID();
    this._bapi.setFilterRange("IT_LRP_RESOURCE_GUID_RA", "I", "EQ", partnerGUID, "");
For ServiceOrderByAccount -
public void setParameters(SAPObject obj)
    throws Exception
    for (GUID object : this._accounts)
      String guid = object.getGUID();
      this._bapi.setFilterRange("IT_ACCOUNT_GUID_RA", "I", "EQ", guid, "");
Question 2 : Why  the filter range in ServiceOrderByMultiResourceScheduling  (MRS Scheduling engine )  is set as - this._bapi.setFilterRange("IT_LRP_RESOURCE_GUID_RA", "I", "EQ", partnerGUID, "");  ? If we see the ServiceOrderByResourcePlanning  also has the same filter range  -  this._bapi.setFilterRange("IT_LRP_RESOURCE_GUID_RA", "I", "EQ", partnerGUID, "");
If these are two different scheduling engines then the table names should be different both in case of MRS and LRP ? Please clarify and explain
Please Explain
Thanks and Regards

Answer 1

Neha,
Got these answers back from the programmer:
Answer 1: Yes, this is being
fetched from the Mobile application configuration parameters as shown below.
The value is configured by a rule to look up to the Service Order MDO
Assignment type filter.
Answer 2: Yes, MRS and LRP are
different scheduling engines, but since the client does not have all the user
information regarding MRS (i.e the resource information), we set the partner
GUID for both. SAP backend ABAP code will determine resource based on the
partner GUID and will call the respective handler for MRS and LRP to retrieve
the service order assignments. Currently Service Manager 4.0 code does not
support MRS with the provided add on.
