try changing your IMPORT DBF file layout to be this:

customer id, quote no, quote date, quote due, quote status, quote price, pid

seed the first record with pid value = 1
then after you import -
locate for empty(pid)
skip -1
m.pid = pid
skip 1
scan rest
m.pid = m.pid + 1
replace pid with m.pid next 1
endscan

that will give you a unique identifier for each record pid - make it integer data type

then ? if you get in a record with everything else the same but the dollar amounts and the pid ? the record with a higher PID value will have the 'latest' data and you can do some math with a prior record and the 'latest' record [for example ! but - you can code up anything you want for *your* inhouse processing, right? ]

you are mentioning QUOTE system and speaking of INVOICE data to somehow
reformulate remaining payments

I think you need some other business process , but I don't want to hammer that concept too much .

In other systems that I've been elbow deep a coding - the QUOTE system was seperate from the INVOICE system, with some linkages when a QUOTE was turned into an ORDER, an INVOICE was generated with the info from the quote.

BUT ? perhaps this is some quote tracking system and you are measuring DIFF's for some other reason ?
