Custom fields in ITS ESS

Question

Hi
I have couple of custom ESS fields on certain infotypes that need to be displayed in ESS. How do I do this.
For example my Previous employers IT has three additional fields in the back end, but hwen I try to get these fields to portals via PZ28 service, the custom fields do not appear. Do I need to do any thing specific to get the fields avialable on the ESS.
Even the Function module 'HR_ESS_PREVEMPERDETAIL_13' that i sused to display these fields does not get the custom fields. I debugged this FM but to no use.
Appreciate any guidance here
regards
Raj

Hi,
I assume you must have done Steps 1 - 4, and must have  missed out Step - 5
Check List
1) The FM HR_ESS_PREVEMPERDETAIL_13 is found in the Function group : EHA10
Copy the same to ZEHA10.
The corresponding function modules are copied to Zxxx.
2) Add the required fields to the screen (200 for the Detailed; 100 for Overview)
   and the neccesary code handling it.
You will find the point where you need to add your code while debugging the Std TCode
Eg:- For save : You can add code to the include LZEHA10F01 Line 416
ie; After
if modus eq update_mode.
perform call_change
             using p0023      "BAPI call
            old_p0023
            return.
if return-type ne space.
3) Save and activate the Function group
4) Take the TCode in se93. You will find it refering to the Pgm : SAPMPZ28
Simply copy the TCode to ZPZ28; Keeping the rest of the parameters the same.
5) Take the Customizing table T77WWW_SC. (In SM30)
This keeps tracks of all services in ESS
Select the records for PZ28 (Previous Employer) and Copy the records to ZPZ28 and
make sure the corresponding Function modules are Zxxx (your FMs).
This should take care of your Customised approach of handling Previous Employer Service.
