ESS Portal W2 Reprint

Question

1. We are facing a problem for W2 Reprint workflow in ESS Portal. The workflow WS01000090 gets triggered when the W2 screen comes up for intercompany mail and the mail is sent to HR administrator inbox.
The work item is set to status completed after the administrator processes the work item,but there is no output of the W2 form in the spool. The problem  seems to be missing data in V_5UXY_A  for year 2008 and hence the submit program RPCTRPU0 is not working. We are displaying the W2 Employee copy form  which is HR_F_W2_MULT_07.The Tax reporter PU19 is working fine in ECC 6.0.
Please let me know if there is any documentation regarding the configuration of V_5UXY_A,T51T5,T5UT8,T5UT7,T5UT6.
2. Also let me know if there is there any standard functionality on ESS Portal to display/render  W2 tax forms on EP Screens in PDF or sapscript format,or do we need to develop custom program/Function module to display W2 forms. Our requirement is to display all previous years W2 forms on EP for employees.

Answer 1

1)  You have to maintain table T51T5 in order for the WF (W2Reprint) to generate the PDF file to the spooler.
Follow this answer from SAP: 
As of 2007, a new form has been introduced HR_F_W2_MULT_07.
The application picks up as default the form that is maintained in the table T51t5 with sequence number 02 for event 4. The new form has been delivered, for event 4 with sequence number 02. So you can rectly the problem by accessing the view V_t51t5, choose the molga-10, Way of reporting - 5 and for tax form HR_F_W2. In the list of entries, for No:2 and event 4, for which HR_F_W2_MULT_01 is maintained, please change the same to HR_F_W2_MULT_07.
2) Create a small program to call the Method W2Reprint in the 01000090 Workflow to generate the employee W2 reprint PDF file.
3) Create a Web App using [Web Dynpro for ABAP|https://wiki.sdn.sap.com/wiki/display/WDABAP/A%20Simple%20Web%20Dynpro%20Application%20to%20display%20a%20pdf%20file%20in%20the%20browser%20window] to display the generated PDF file from the spooler.  (Remember to add code to WDDOINIT in the Main View, to read the generated PDF file)
