SAP Error Message - Details

• Message type: E = Error

• Message class: FMHIE - Budget Hierarchies

• Message number: 430

• Message text: Inconsistent hierarchy data: invalid next sibling definition for ID &1

What causes this issue?

The 'next sibling' definition for at least one child node of the budget

inconsistent.
Possible reasons for this inconsistency are as follows:
At least two child nodes have no next sibling (there must be exactly one
child node without next sibling)
One child node has as next sibling a multi-level node, which is not a
child node of the multi-level node &V4&
One child node has itself as next sibling
Two or more child nodes reference each other as next sibling

System Response

The multi-level budget structure cannot be processed for hierarchy ID
&V1&.

How to fix this error?

Check the definition of the 'next sibling' for all child nodes of the
budget address &V2&&V3& (hierarchical part) in hierarchy ID &V1&.

• What is the cause and solution for SAP error message FMHIE430 - Inconsistent hierarchy data: invalid next sibling definition for ID &1 ?

  The SAP error message FMHIE430 indicates that there is an inconsistency in the hierarchy data, specifically related to the definition of a "next sibling" in a hierarchy structure. This error typically arises in the context of hierarchical data structures used in SAP, such as those found in Financial Management (FM) or other modules that utilize hierarchical data.
  Cause:
  The error message FMHIE430 is triggered when the system detects that the definition of a "next sibling" for a particular hierarchy node (identified by ID &1) is invalid. This can occur due to several reasons, including:
  
  Corrupted Hierarchy Data: The hierarchy data may have been corrupted due to improper updates, deletions, or modifications.
  Incorrect Configuration: There may be an issue with the configuration of the hierarchy, such as incorrect parent-child relationships.
  Data Migration Issues: If data was migrated from another system or from a previous version of SAP, inconsistencies may have been introduced.
  Manual Errors: Manual changes to the hierarchy structure that do not adhere to the required rules can lead to inconsistencies.
  
  Solution:
  To resolve the FMHIE430 error, you can follow these steps:
  
  
  Check Hierarchy Structure: Review the hierarchy structure for the node identified by ID &1. Ensure that the parent-child relationships are correctly defined and that there are no missing or extra nodes.
  
  
  Use Hierarchy Maintenance Transactions: Utilize SAP transactions such as FMHIER (Hierarchy Maintenance) or FMHIER1 to check and correct the hierarchy data. Look for any inconsistencies in the hierarchy and make necessary adjustments.
  
  
  Rebuild the Hierarchy: If the hierarchy is significantly corrupted, it may be necessary to rebuild it from scratch. This involves deleting the existing hierarchy and recreating it with the correct structure.
  
  
  Check for Data Migration Issues: If the error occurred after a data migration, review the migration process to ensure that all data was transferred correctly and that the hierarchy structure was maintained.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates that can resolve known issues related to hierarchy inconsistencies.
  
  
  Contact SAP Support: If the issue persists after attempting the above solutions, consider reaching out to SAP Support for further assistance. Provide them with detailed information about the error and the steps you have already taken.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes for hierarchy maintenance, such as FMHIER, FMHIER1, and others that may be specific to your SAP version.
  Documentation: Review SAP documentation related to hierarchical data management in the specific module you are working with (e.g., Financial Management).
  Testing: After making changes, conduct thorough testing to ensure that the hierarchy functions as expected and that the error does not reoccur.
  
  By following these steps, you should be able to identify and resolve the cause of the FMHIE430 error in your SAP system.
