Llamada a transacción en JOB de fondo

[nievesmp]

Tengo una llamada vía JOB:


CALL FUNCTION 'JOB_OPEN'
EXPORTING
JOBNAME = JOBNAME
JOBCLASS = c_a
IMPORTING
JOBCOUNT = JOBCOUNT
EXCEPTIONS
CANT_CREATE_JOB = 1
INVALID_JOB_DATA = 2
JOBNAME_MISSING = 3
OTHERS = 4.

SUBMIT SAPF124 user SY-UNAME VIA JOB JOBNAME
NUMBER JOBCOUNT
WITH BUKRX in s_bukrs
WITH KONTS in s_konts
* WITH KONTS in s_konts
WITH XAUSBEL = 'X'
WITH XNAUSBEL = 'X'
WITH X_FEHLER = 'X'
WITH X_SAKNR = 'X'
WITH X_TESTL = ' '
AND RETURN.

CALL FUNCTION 'JOB_CLOSE'
EXPORTING
JOBNAME = JOBNAME
JOBCOUNT = JOBCOUNT
STRTIMMED = 'X'
EXCEPTIONS
CANT_START_IMMEDIATE = 1
INVALID_STARTDATE = 2
JOBNAME_MISSING = 3
JOB_CLOSE_FAILED = 4
JOB_NOSTEPS = 5
JOB_NOTEX = 6
LOCK_FAILED = 7
OTHERS = 8.

Pero me devuelve el sy-subrc = 5 (JOB_NOSTEPS), al final me da me ejecuta en abierto y me da un dump seálándome error por job_nonstep.

¿A que se debe esto?

Muchas gracias de antemano.
