Hi Jeff,

Great...really helpful! You're not misunderstanding--you're right on track.
The combined file doesn't yet look like that because the ID field is, indeed,
an autonumber. So, if I understand you when you say:

"When I appended the records, I'd be putting the ID numbers into a new
Numeric/LongInt field (that's the counterpart/equivalent of what Autonumber
generates)."

...you mean that this new field would end up getting the original autonumbers
from the various locations, but the Autonumber ID field in the combined file
would write new autonumbers to any records that were added from other
locations.

So, this leads me to wonder what happens to all the related tables for the
various locations, because all the PK/FK links are using the autonumber field
as the PK and linking to this autonumber for the FK. Is there a way to get
all the FKs to cascade the changes (I've seen reference to cascading) that
will be introduced when the locations are assigned new autonumbers in the
combined file? Or, will I need to migrate the PK in each table to the new
Numeric/LongInt field that I've created?

Again, thanks...

Here's my view of the data in your combined db:

ID Location blah, blah, blah

1 East
2 East
3 East
2 North
3 North
1 West
2 West
4 West
1 South
2 South
3 South
4 South
99 South

Notice that you can have multiple identical IDs (but also note that these
CAN NOT be autonumber type in the combined table!), distinguishable by their
Locations.

To do this, I would leave the Locations/sites doing their thing with their
own Autonumbers, then use a query to append the records into my "master"
table. When I appended the records, I'd be putting the ID numbers into a
new Numeric/LongInt field (that's the counterpart/equivalent of what
Autonumber generates).

Again, DO NOT attempt to append autonumbers (from Locations) into an
autonumber (in main table) field ... and Access won't let you duplicate an
already used Autonumber, so this might be moot!

Good luck!

Thanks, Jeff. Yes, I am using 2007. I'm not sure what the "replication"
feature was, but it sounds like it isn't an option anyway for 2007.
