Items posted twice

hi friends,

we have a problem few items on one of the bank statement are posted twice with a different document number as we ran program rfebka30 twice. the first time the

programs ran the job was cancelled in between, and we had ran the progarm for the second time and now we found that some items were posted twice.

why did this happen?

during the cancelled job few items might have been posted. but when we run

the program for second time. shouldnt the program checks for the items already

posted and just post the remaining items?

i appreciate ur participation

thanks

charlie
