Message class:  FMHIE - Budget Hierarchies 
Message number: 441
Message text: Multi-level node already exists with differing hierarchy relationship
You want to add the node &V3&&V4& (hierarchical part, with node
identifier &V2&) to the multi-level budget structure for hierarchy ID
&V1&.
However, this node already exists in the multi-level budget structure,
with a hierarchy relationship that differs from the new node.
At least the <ZK>parent</> or <ZK>next sibling</> definition is
different from the hierarchy relationship you have specified for the new
node to be added.
The specified hierarchy node cannot be processed.
Add another hierarchy node or first remove the existing multi-level node
&V3&&V4& (hierarchical part) from the multi-level budget structure.

Hierarchy Structure Conflict: The existing hierarchy structure does not allow for the new node to be added in the way you are attempting. Data Inconsistency: There may be inconsistencies in the data that prevent the system from recognizing the intended relationship of the new node.
Solution: Check Existing Hierarchies: Review the existing hierarchy structure to see if the node you are trying to create already exists. You can do this by navigating to
