If your Accounting Export File is blank it means during the session balancing that the user pushed the GET DEPOSIT button twice which grabs the next deposit number so it can create the totals on the bank deposit report.  For example, if 8 was the first deposit number grabbed when pushed,  then 9 was the second push of the Get Deposit button so when she completed the RECORD DEPOSIT and MARKED the session as balanced it stamped the last number used "9" on the actual line items.  SO 8 only had SUMMARY line items in the gltran which do not get exported to accounting software hence creating what appeared to be a BLANK accounting file for session 8.
