How To Fix FMHIE435 - Multi-level node becomes leaf node when its subordinate nodes are deleted

FMHIE435 - Overview

• Message type: E = Error

• Message class: FMHIE - Budget Hierarchies

• Message number: 435

• Message text: Multi-level node becomes leaf node when its subordinate nodes are deleted

What causes this issue?

The multi-level node &V3&&V4& (hierarchical part, with node identifier
&V2&) becomes a new leaf node for the <DS:DE.FMHIE_HIE_ID>hierarchy ID
</> &V1& after its subordinate nodes are removed.
Since the multi-level node &V3&&V4& is already used for budgeting and
the following <ZK>BA definition rule</> is used for the hierarchy ID
&V1&: <ZH>All Addresses Except Leaves are Valid Budget Addresses</>, the
deletion of multi-level nodes leads to inconsistencies.

System Response

The subordinate nodes for the multi-level node &V3&&V4& (hierarchical
part) may not be deleted from the multi-level budget structure.

How to fix this error?

Only delete multi-level nodes in such a way that new leaf nodes are not
already used for budgeting.

FMHIE435 - Details

• The SAP error message FMHIE435 indicates that a multi-level node in a hierarchical structure has become a leaf node because its subordinate nodes have been deleted. This typically occurs in the context of hierarchical data structures, such as those used in Financial Management (FM) or other modules that utilize hierarchical representations of data.
  
  Cause:
  
  Deletion of Subordinate Nodes: The primary cause of this error is the deletion of subordinate nodes (children) from a multi-level node (parent). When all subordinate nodes are removed, the parent node no longer has any children, thus it becomes a leaf node.
  Data Integrity Rules: SAP enforces data integrity rules that prevent certain actions when they would violate the hierarchical structure. If a parent node is left without children, it may trigger this error.
  
  
  Solution:
  
  Check Hierarchical Structure: Review the hierarchical structure to ensure that you are not unintentionally deleting all subordinate nodes of a multi-level node. If you need to
