>That depends on the 1st parameter in tableupdate() - check to see what your framework uses there. It may go one record at a time so it can check each record (postsave etc) or do them all at once and then get recno()s (of those causing an error) in an array (last parameter of tableupdate()) or it may not even care. Look under the hood.

Disagree. Unless reasons are given for a specific problem, ***always*** use table buffering - if biz logic needs working via single record tableupdates, implement logic to fire for each record - do not let possible "vfp-automatic" record pointer move fire record saves.
