Getting Dump while using PYXX_READ_PAYROLL_RESULT FM

Question

I m trying to get the gross salary and ESI contribution amount for an indian based employee. While using the FM 'PYXX_READ_PAYROLL_RESULT' i m getting the following dump.
************************************************************************************************************************************************************An exception occurred that is explained in detail below.The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_TYPE', wa  not caught in  procedure "PYXX_READ_PAYROLL_RESULT" "(FUNCTION)", nor was it propagated by  RAISING clause.Since the caller of the procedure could not have anticipated that the exception would occur, the current program is terminated. The reason for the exception is:
Call to FORM "IMPORT_RESULT" is incorrect:
The actual parameter no. 2 has a different data type in the
PERFORM than requested for the FORM "IMPORT_RESULT" in program  %_T06K40".    
and it is showing the dump result here
ELSE.
      PERFORM import_client_spec IN PROGRAM (subroutine_pool-name)
                                  USING client
                                         key
                                         payroll_result
                                         import_subrc
                                         pcl2_version_number
                                         typepool_version_number
                        IF FOUND.
Pls help me to solve the issue as it very high priroty work

Hi Faisal,
Before the FM the Sy-Subrc is zero only and i have declared the exception part also..
IF sy-subrc = 0.
  CALL FUNCTION 'PYXX_READ_PAYROLL_RESULT'
    EXPORTING
      clusterid                    = 'IN'
      employeenumber               = P0001-pernr
      sequencenumber               = it_rgdir-seqnr
      filter_cumulations           = ''
    CHANGING
      payroll_result               = it_payresult
    EXCEPTIONS
      illegal_isocode_or_clusterid = 1
      error_generating_import      = 2
      import_mismatch_error        = 3
      subpool_dir_full             = 4
      no_read_authority            = 5
      no_record_found              = 6
      versions_do_not_match        = 7
      error_reading_archive        = 8
      error_reading_relid          = 9
      OTHERS                       = 10.
  IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
Endif.
Thanks!
