The problem is that if one user is editing a record, you may find that
lots of other records (typically 30-50) are also locked. This is
because Access stores its data in "pages" of data that are 2k in size,
so any record that is locked on the page will automatically lock all
the others.
You have three strategies for record locking. You can change these in
the form's "Record Locks" property.
1. No Locks (the default)
User 1 starts editing a record. User 2 then starts editing the same
record. User 1 exits the record, thus saving their changes. User 2 tries
to exit the record - they will receive the error message "This record
has changed since you started editing it", and are given the options to
either save their changes (thus overwriting User 1's changes) or copy
the record to the clipboard for possible insertion later.
2. Edited Record
This is, I suspect, what you are currently implementing. One user
editing a record in a "page" of data will lock a number of other
records. The locks are released when the user saves the record.
3. All records
Totally inflexible - only one user at a time can edit any record in
the table.
It's worth pointing out that Access XP and the new Access 2003 have
changed the strategy so that when a user edits a record, only that
record is locked and not the whole page.
Try searching on "Record Locking" in Access Help for more information.
Hope this helps and good luck.
