>>If you mean that you use VFP interface connected to VFP tables using remote views, than you probably took wrong way, just because using local views you will get the same thing but avoid one (redudndant, in this case) ODBC layer. Surely, unique ID generation will work the same way in both cases.

Remore views and ODBC are both used when you should connect to non-VFP data source (usually RDBMS as SQL-Server,Oracle,Sybase,etc). If you use VFP data you should take normal way working with local views and/or plain tables. Local view is always exclusive because it always exists locally, so don't worry about this. Actually multi-user integrity supported by buffering and generic app flow.
