Method to assign custom iViews in the MSS General Info page in NW 7.4

[FabricioPereira]

Hello,

We are migrating the Portal applications from our Portal NW 7.02 to NW 7.4 and we are having issues to integrate some WD Java applications in the MSS General Information page. Our backend is ECC 6.0 EHP4.

These are the steps we are following:

• Create WD Java application. We can execute it standalone successfully.
• In the Portal, we created the view for this WD Java app using the Self-Service Administrator
• We assigned the View to the FPM application “General Information” under Self-Service Administrator >> Portal Content >> Content Provided by SAP >> srvconfig >> com.sap.pct.erp.srvconfig.mss >> Employee Profiles >> FPM Applications >> General Information
• After restarting the Portal, I can see the view under the application page of the mss~eepro/General information in the Content Administration >> Portal Content Management >> Web Dynpro Java Applications >> mss~eepro >> General information gwd:/mss~eepro/com.sap.xss.hr.eeprofile.GeneralInformation_base
• We copied the GeneralInformation and pasted it as pcd content under one of our folders.
• The new iView was not created at that moment. We had to go back to the mss~eepro application, right click on it and select the option “Update PCD Objects” for the iView to appear under the recently created General Information page.
• The problem happens when we try to preview this page. We receive a HTTP 500 message error
• Would you have any idea of what might be missing in our configuration or code?
• In the old NW 7.0x, we were following the blog but on NW 7.4 we cannot create iViews as before. Blog http://wiki.sdn.sap.com/wiki/display/profile/How-to%20add%20a%20custom%20Web%20Dynpro%20iView%20to%2...
• That’s the error we get:

500   Internal Server Error

• The initial exception that caused the request to fail, was:

[Former Member]

Hello,

We are facing the same problem.

Could you,please, share with us how you managed to fix it.

Thank you.

if you can execute it successfully in standalone, then you need to check the URL  or roles, You can do a HTTP trace and see what URL getting generated
