HCM forms Advanced Generic service

Question

Hi,
I am using HCM FPM forms Advanced Generic service to update Action infotype (0000). In the flush method i call the funciton module 'HR_CONTROL_INFTY_OPERATION'.
while executing update application throws error 'Precondition violated'.
I have pasted the code lines below. Please let me know if anything is missed out.
METHOD if_hrasr00gen_service_advanced~flush.
   DATA: ls_pa0000 TYPE p0000.
   DATA: ret TYPE bapireturn1.
   ls_pa0000-pernr = gv_empno.
   ls_pa0000-endda = '99991231'.
   ls_pa0000-begda = sy-datum.
   ls_pa0000-massn = 'K2'.
   ls_pa0000-massg = '01'.
   ls_pa0000-STAT2 = '3'.
CALL FUNCTION 'HR_CONTROL_INFTY_OPERATION'
   EXPORTING
     infty                  = '0000'
     number                 = ls_pa0000-pernr
     record                 = ls_pa0000
     operation              = 'INS'
  IMPORTING
    RETURN                 = ret.
ENDMETHOD.
Below is the error message.
The following error occurred in system XXX : Precondition Violated
The error occurred on application server XXXXXX_00 and in work process. 5
The termination type was: RABAX_STATE
The ABAP call stack was:

You have to be a bit careful using that function. If you look, the first thing it does is to check WHICH framework to use (old or new)...and oddly, for for infotypes 0000,0001,0003,0031 and 200n, it ALWAYS forces it to use the old framework. (ugg!)
As said above, for HCM P&F, you should be using the DCIF, so make sure you know which infotypes you need to "touch" before using the function over the decoupled IT/buffer container class handling.
Lastly, why are you trying to do this for IT0000 anyways? The framework does this for you automatically when you assign MASSN and MASSG (SAP_PA picks those up as "special fields" and creates the IT0000 for you). If you need to manipulate the values for action and action reason, use a simple generic service to set/assign the fields and still let the framework handle it automatically for you in SAP_PA.
oh! ....and TCLAS and DIALOG_MODE are not optional parameters of the function.
