What causes this issue?

During the period between &V3& and &V4& person &V1& will have holder
relationships to further positions. As this person hasn't previously
been assigned to a position, and was therefore assigned to the default
position, records of a predecessor will not be updated. The only thing
that needs to be maintained for deleted infotype 1 are the
holder relationships for person &V1& which have previously been
displayed in personnel planning.
