Hi regarding parrelel processing of the program

Question

Hi Experts,
       1.I have 2 records in one file which are processing by one program.
       2.This program is calling one function module ,this function module is processing the records.
       3.In that function module,there is one user exit where we have written code to process the record.
       4.The flow is like below ,
           Program> RFC Function module>Userexit.
       5.After control passed to function module, the program is processing another record.
          but still the user exit in the function module may not complete the processing of first record.
          Because of this , sometimes, 2 records are running the user exit at a time.
          But the 2nd record processing depends on first record result.
          Because of this sometimes  2nd record is getting incorrect result.
          How can i let the user-exit code  wait not to process the 2nd record before completion of first record.
           Thanks&Records

Thanks everybody for valuable suggestions.
Actually i used the functiuon module :
data : prg type INDX-SRTFD value 'ZTEST1_CHECJ'.
if count ne 1.
endif.
do.
CALL FUNCTION 'ENQUEUE_ESINDX'
EXPORTING
   MODE_INDX            = 'E'
   MANDT                = SY-MANDT
   RELID                = 'ZZ'
   SRTFD                = prg
  SRTF2                =
  X_RELID              = ' '
  X_SRTFD              = ' '
  X_SRTF2              = ' '
  _SCOPE               = '2'
  _WAIT                = ' '
  _COLLECT             = ' '
EXCEPTIONS
   FOREIGN_LOCK         = 1
   SYSTEM_FAILURE       = 2
   OTHERS               = 3
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
else.
exit.
ENDIF.
like above till sy-subrc = 0. i can let the program wait .
I guess it will work.
Finally here they have changed the design itself, to avoid dependency records.
So no issues
Thanks
