LOAD_SCRIPT and deletion of log files

Gents, I have a strange (to me anyway) issue.

I have a job (JOB A) that calls a number of different jobs. One of these called jobs (JOB B) has the following step:

#================================================= ================
# STEP 05. Load into staging table
#================================================= ================
STEP
. ${LOAD_SCRIPT}
ENDSTEP

...the LOAD_SCRIPT is this: LOAD_SCRIPT=${WFM_BIN}/bulkload_${TABLENAME}_ld.ksh

...so, as you can see these simply load data via db2 load commands. In JOB B i use this: LOAD_ERR=${EDR_LOG}/${JOBNAME}_load_errors.log to capture DB2 messages. The issue is, i can delete the logs upon successful completion by putting in a rm -f command in JOB A...but, why cant i put this rm in JOB B instead?- I would like the JOB B which creates the logs to also be the job that removes them. If i do, it does not remove the logs...it only removes the logs when JOB A has the rm command. I thought maybe the LOAD_SCRIPT has a hold on the logs but i would think the ENDSTEP should be releasing it. Of course the rm command is at the very bottom of JOB B.

Thanks
B
