Diagnosis
The segment &v3& does not occur at the current level of the basic typeV1 (extension v2).
This error can have several reasons:

• The segment &v3& is assigned to a group whose header segment does not
occur.

• The segment &v3& does not exist in the syntax description of the basic
type &v1& (extension &v2&).

• The sequence of segments in the group in which the segment appears is
incorrect.
Previous errors ('mandatory' segment or group missing) may be due tothis error.
