>We have a vfp front-end app with sql 2k5 backend that use remote views. For the remote views, we've been using WhereType = 3 so far without major problems. Recently we are researching about using WhereType = 4 (timestamp) mainly for performance reason, among others.

Added timestamp in sql table, modified an updatable remote view to include timestamp column in the select clause, WhereType to 4, etc. Ran a data-entry form in the app that update/delete/insert using this remote view, and the form seems to save fine the first time. If I make another change WITHOUT exiting the form, and click save, then I get a 'update conflict' error.

Timestamp field changes every time the record is updated. So if you're trying to update the same record by old timestamp, it won't find it.
