Keith
in another discussion you stated
  Sage 50 has the function to see which user makes the journal entry by going to
  Reports, Transactions Details, All with a check mark to User.  
  This only applies to invoice because there is no entry posted to the book
  when it is an order or quote.

I presume you meant
  reports->journal entries -> all

when I do that, and I check 'user', it doesn't allow me to filter which user I would like to
report on - or is there a way to filter by user in Sage, that I'm missing ?

and the report is really a who-dunnit report, not an audit trail
for example
   apr 1, Keith creates a sales invoice, price 100$
   apr 12, Roger incorrectly changes the invoice's price by giving a 10% discount
   apr 15, someone is trying to see the history of what happened with this invoice, ie. the initial transaction and the modification

the user checkbox with a date range of Apr 12th, will show Roger's change, but will not show both transactions

the same report with a date range of Apr 1-12, doesn't group the transactions for this invoice together

is there a way to show both transactions in Sage, grouped together ?
