ESS Information errors if end date is less than system date

Question

Hi to all,
I have create an WD Java aplication to create new entries in infotype 0023.
First problem: At the beginning I couldn't create new entries if start date is less than system date. To solve this problem I used:
The transaction SPRO to go to Personnel Management>Employee Self Service>Service Specific Setting-->Change Default Start Date
In HRXSS_PER_BEGDA I changed BEGDA to 01.01.1900 in the DEFAULT_DATE method and i solved the first problem.
Now I need solved the second problem - we couldn't create new entries if end date is less than system date.
In this method DEFAULT_DATE I can't change ENDDA because ENDDA isn't a parameter in this method.
MOLGA (Importing)
PERNR (Importing)
INFTY (Importing)
SUBTY (Importing, optional)
BEGDA (Changing)
Can anybody helps me about this second problem?
Thank a lot for your help.

Answer 1

I am creating an aplication WD Java:
- This application uses a R3 Function Module HRXSS_PER_MODIFY_PNNNN
- This FM uses the method CALL METHOD xss_adapter->modify
- This Method uses IF_HRPA_PERNR_INFTY_XSS~MODIFY
- This method uses:
  IF buffer_entry-container->a_pskey-endda < user_today.
    msg-msgid = 'PG'.
    msg-msgty = 'E'.
    msg-msgno = '016'.
    msg-msgv1 = 'Data valid only for past is not'(009).
    msg-msgv2 = 'allowed;'(010).
    msg-msgv3 = 'correct'(011).
    msg-msgv4 = 'end date to a date today or future date.'(012).
    CALL METHOD message_list->if_hrpa_message_handler~add_message
      EXPORTING
        message = msg
        cause   = xss_adapter_generic.
  ENDIF.
How can I change the value user_today?
This value is a parameter for the method GET_INSTANCE in CL_HRPA_PERNR_INFTY_XSS, but I don't know when this method is called.
Can you help me?
