Skills Profile - Enhance Web DynPro to handle Effective Date

Question

We are working with the ESS BP on ECC 6.0 and have a requirement to enter an Effectivity Date for the start of a qualification.  The trouble is that the existing function for updating the qualification profile (XSS_SKL_APPLY_QUALI_PROFILE) does not allow for a beginning date to be passed in.  Instead it uses the current date (Sy-Datum) which is set on initialization of the SkillsApplication (via FM XSS_SKL_INITIALIZE_DATA).  I have tried to enhance the structure for the qualification profile (structure RHXSS_SKL_EMPLOYEE) but it is marked as Can Not be Enhanced by SAP.
Does anyone have any thoughts on a good way to add this functionality?  I'd hate to throw away all of SAP's work with the SkillsApplication and write one from scratch just for this small change, but it's looking like that might be my only option.

Answer 1

The following describes the changes required for adding the effectivity date to the Standard Skills Profile Web Dynpro Java screen.
ABAP Changes
1.  Get modification keys for hte following structures and change the enhancement category of the strucures to "Can Be Enhanced Deep".
     RHXSS_SKL_EMPLOYEE
     RHXSS_SKL_PROF_UPD
     RHXSS_SKL_QUALIPROFILE
2.  Add appends to each of the structures in step 1 for feidl ZEFFDATE
     RHXSS_SKL_EMPLOYEE - ZZEFFDATE type BEGDATUM
     RHXSS_SKL_PROF_UPD - ZZEFFDATE type String
     RHXSS_SKL_QUALIPROFILE - ZZEFFDATE type BEGDATUM
3.  Enhance the following function modules for setting/getting the values of ZZEFFDATE
     XSS_SKL_APPLY_QUALI_PROFILE
     XSS_SKL_CONFIRMATION_DATA
     XSS_SKL_GET_PROFILE_OVERVIEW
     XSS_SKL_GET_QUALI_DETAIL_DATA
4.  Enhance the following Includes using the Modification Assistant or Enhancement Framework for setting/getting
    LRHXSS_SKL_INTERFACEF01
    LRHXSS_SKL_INTERFACETOP 
Java Changes
Track:  Make a new track for the ESS Component.  A quick SDN search should produce for you a Cookbook for setting this up in the NWDI
DC:  esssklsap.com
1.  Reimport the Skills model to get the ABAP changes into WebDynpro
2.  Create a new Application (zSkillsApplication in my case)
3.  Modify the Application properties to tell the framework manager to use the CcSklConfiguration  component for navigation configuration
     Properties
     sap.authentication = true
     sap.xss.configurationComponentDC = sap.com/ess~skl
    sap.xss.configurationComponentName = com.sap.xss.hr.skl.CcSklConfiguration
4.  In the Interface Controller of Component CcSklConfiguration, modify the navigation Graph as follows
navigationGraph =
   new NavigationGraph(
    new NavigationPath[] {
     new NavigationPath("",IFPM.EVENT_START,"OVERVIEW"),
     new NavigationPath("OVERVIEW",IFPM.EVENT_EDIT,"DETAIL"),
     new NavigationPath("OVERVIEW",IFPM.EVENT_ADD,"SELECT"),
     new NavigationPath("OVERVIEW",IFPM.EVENT_REVIEW,"REVIEW"),
     new NavigationPath("OVERVIEW",IFPM.EVENT_REMOVE, "OVERVIEW"),
//begin replace ERICV - Go Straight to Review&Save
//     new NavigationPath("DETAIL",IFPM.EVENT_ADD, "OVERVIEW"),
     new NavigationPath("DETAIL",IFPM.EVENT_ADD, "REVIEW"),
//end replace ERICV - Go Straight to Review&Save    
     new NavigationPath("DETAIL",IFPM.EVENT_BACK, "OVERVIEW"),
     new NavigationPath("DETAIL",IFPM.EVENT_SELECT, "SELECT"),
     new NavigationPath("SELECT",IFPM.EVENT_EDIT, "DETAIL"),  >
5.  In the Component FcSklBusinessLogic, make the following changes:
        a.  Perform the context mapping of the new ZZEFFDATE field in the Interface Controller and Standard Controllier
        b.  Modify the insUpdSkill method of the Component Controller to populate the Effective Date
try {
   wdContext.nodeApply_Quali_Profile_Input().bind(
    (Xss_Skl_Apply_Quali_Profile_Input) model.createModelObject(Xss_Skl_Apply_Quali_Profile_Input.class));
   Xss_Skl_Apply_Quali_Profile_Input input = new Xss_Skl_Apply_Quali_Profile_Input();
   Rhxss_Skl_Employee insUpdVector = new Rhxss_Skl_Employee();
   insUpdVector.setSkill_Id(wdContext.currentContextElement().getQualiId());
   insUpdVector.setExist_Profcy(wdContext.currentContextElement().getProfDropDown());
   //Begin Insert ERICV - Add Effective Date to Skills Qualification
   insUpdVector.setZzeffdate(wdContext.currentContextElement().getZzEffDate());
   //End Insert ERICV - Add Effective Date to Skills Qualification
   input.addProfile_Ins_Tab(insUpdVector);
   wdContext.nodeApply_Quali_Profile_Input().bind(input);
   wdContext.currentApply_Quali_Profile_InputElement().modelObject().execute();
  } catch (Exception ex) {
   fpm.getMessageManager().raiseException(wdThis.wdGetAPI().getComponent(), ex);
6.  In the Component VcSklDetail make the following changes:
     a.  Context mapping of all relevant nodes to get the new ZZEFFDATE field in the context
     b.  Screen modifications to get the ZZEFFDATE on the screen
     c.  Modify the initDetail method of the Component Controller
if ((sklOutputElement.getExpiry_Date() == null) || (sklOutputElement.getExpiry_Date().equals(""))) {
   wdContext.currentContextElement().setLicenceVisibility(WDVisibility.NONE);
//begin insert ERICV - set the zzEffective Date
     //convert date to java.util.date
         SimpleDateFormat sdf = new SimpleDateFormat("mm/dd/yyyy");
  try {
   java.util.Date myDate = sdf.parse(wdContext.currentGet_Quali_Detail_Data_OutputElement().getStart_Date());
   sdf.applyPattern("yyyy-mm-dd");
   wdContext.currentContextElement().setZzEffDate(Date.valueOf(sdf.format(myDate)));
  } catch (ParseException e) {
   // TODO Auto-generated catch block
            e.printStackTrace();
//end insert ERICV - set the zzEffective Date
    //@@end
