Unposted Receivables Journal Lines

We have unposted lines in RA_CUST_TRX_LINE_GL_DIST_ALL (Unposted Totals by GL Date and Class) according to a Transaction diagnostic report run for a debit memo. The unposted lines are causing our AR Recon Rpt to be out of balance. Running Submit Accounting doesn't pick up the unposted lines, nor do they show up on a Journal Entries Report run for unposted journals. However, when I run Submit Accounting with Create Accounting in draft mode, the lines appear on the output report.  What do I need to do to process these unposted lines?  Thanks!  Wayne
