Hi Sylvain,

>> VFP need to lock the header of the table a fraction of a second when adding new record. If another user try to insert a record while another user as a lock on the header, you get a error message.
2 suggestions:
- Turn on record/table buffering and check the result of TableUpdate() (my preffered choice)
- Issue a RLock(0) before inserting the new record and release it afterward. RLock(0) will lock the header of the table>>
I will try buffering (and Ed's idea on SET REPROCESS TO AUTOMATIC).

Thanks!

Vern
