Intelligence Sales Report does not tie to P&L

SOLVED

When I run a standard Customer Sales report in Intelligence for a month (Nov in this instance) it does not tie to the PL or sales recap report .  Intelligence is typically higher than the PL.  I can trace it to a specific product line but I don't see anything that stands out in those invoices that would lead sale to be 30-40K higher than the PL.  It does not appear to be rebate or discount related.

Any ideas on what would cause the difference or how to begin reconciling the reports?

EDIT: I assume it may be that the customer sales report uses invoice date which is not necessarily the same as the posting date.
