Hi everybody,

I'd like to understand if the behavior we're getting with transactions is what we should expect or there is some anomality here.

Here is the scenario:

When doing imports we put table buffering on bunch of our tables: Trans, Patients, Names, Address, Phones, etc. We then do various processes with the tables (inserting data or modifying data). Finally when it's time to commit the changes we do
begin transaction
  llUpdate = tableupdate(.t.,.t.,"First Table")
  if not llUpdate
     rollback
     tablerevert all the changes done previously
     close the process && That logic is done in a separate method
  endif
  ...
end transaction
Now in the separate VFP session we try to open tables used in the process. Prior to executing tableupdate we can open and close the table. But once the tableupdate is issued, we're getting "File is in use" error.

So, is it the right behavior? The changes for that table are already happened through tableupdate, though the transaction is not yet closed.

Thanks a lot in advance and suggestions.
If it's not broken, fix it until it is.
