That really depends on how the /copy/ is implemented. The OP never stated explicitly what implemented their "copied" activity. IIRC the CPYF always has the effect of having specified the OVERRIDING SYSTEM VALUE clause on an INSERT; for which, if there is no column matching the identity in the target, the value is GENERATED, instead of the error SQL0109 being issued like if the request had been actual SQL. So very likely, the OP used CPYF to effect the copy activity.?
