Glenda,
One thing you could do would be to add a field to the table definition
with a date/time format. Then get your entry form to write the NOW()
value to that field whenver a record is updated.
I'm assuming you're opening the whole table as a recordset. Instead, you
can use an SQL string just to load updated records into the recordset by
putting a WHERE satement in the SQL to only include records with
date/timestamps later than the last 'systemcheck' date and time.
Every time you run your routine, you can write a NOW() value to a
special table which overwrites the last 'systemcheck' date and time.

Subject: [mso] Access - Matching
Hi.
I run a process every couple of days that takes data from one source and
posts it to another. I've been working out the bugs in the process and
still need to work on Greg's suggestions for automating but in the
meantime, here's a question to kick-around.
The data file contains 25 rows. Currently, every record, which can be
thousands, is handled every time the process is run. What I really want
to do though is only process records where something has changed in any
one of the 25 fields.
How might this be accomplished?
Thanks. /g
