EasyAcct Convert to Quickbooks Enterprise

I am currently trying to export data from EasyAcct to Quickbooks Enterprise. I can export all of the summaries to .CSV files with no problem. However, I would also like to export individual A/R transaction entries from the A/R module. I have figured out where all of the individual data is stored, except for quantity information. figuring this out would save my client dozens of man hours of re-entering transaction data.The tests I have run seem to work fine for some data values, but not others. I have written a conversion program to parse the data and convert to Excel that can then be imported into Quickbooks. Everything works except the quantity. Any ideas on where the line-item quantity information is stored? Thoughts?
