Hi Folks, Thaks for all your help.

What worked was:
>>>>>SET IDENTITY_INSERT MYTABLE ON (***** NOT OFF *****)
>>>>>IMport the VFP data
>>>>>SET IDENTITY_INSERT MYTABLE OFF (***** NOT ON ***)

Sql seems to look at the highest Key and assign the next highets number
Still dont know what hapens if I have Gaps and I reached the highest number... does it use the gaps or error out
Regards,
Gerard
