Introduction

I was surprised not to find any examples on how to modify the start and/or end dates of PA infotypes using the decoupled framework. Typically the start and end dates are part of the key identifying the record. Unless you know what you are doing, you will most likely get a CX_HRPA_INVALID_PARAMETER exception with the parameter PRIMARY_RECORD-PSKEY. Important here is to have the existing record, create a new one (with new values) and refer the old record when calling the MODIFY method.

Acknowledgements

All the code was copied and adapted from the standard function module HR_CONTROL_INFTY_OPERATION, the decoupled framework parts of it.

To use it, you would simply call the method with all required parameters

  data lt_messages type hrpad_message_tab.

  data lv_ok type boole_d.

  call method change_begda_endda

    exporting

      iv_tclas    = ‘A’

      iv_infty    = ‘0002’

      iv_subty    = ”

      iv_objps    = ”

      iv_sprps    = ”

      iv_seqnr    = ‘000’

      iv_pernr    = ‘12345678’

      iv_begda    = ‘20001201’

      iv_endda    = ‘99991231’

      iv_begda_new = ‘20101201’

      iv_endda_new = ‘99991231’

      iv_test_mode = ‘ ‘

    importing

      et_messages = lt_messages

      ev_ok       = lv_ok.

This would change the start date of infotype 0002 for employee 12345678 from 12/01/2000 to 12/01/2010.

Limitations

I’m sure there are many situations where the code will break. For example, I didn’t bother with secondary records and the code handles only one record at a time. In addition the code should check that the decoupled framework can actually be used for the infotype in question. Nevertheless, I thought I’d share this as it may help folks out there.
