since the roles of the superior position &V2& and the subordinate
position &V1& would conflict in the investment program hierarchy.

How to fix this error?

Only the following combinations are allowed:
Superior position has value '2' (totals position) - subordinate
position can have value '2' (totals position) or '1' (strategic program
position) or remain blank.
Superior position has value '1' (strategic program position) -
subordinate position can have value '1' (strategic program position) or
remain blank.
The values of superior position and subordinate position remain blank.
(Refer also to the F1 help for the "role in hierarchy" field in the
