How To Fix RH094 - The hierarchy contains multiple root node (Only one is displayed)

SAP Error Message - Details

• Message type: E = Error

• Message class: RH - BW: Hierarchies ( basic functions )

• Message number: 094

• Message text: The hierarchy contains multiple root node (Only one is displayed)

What causes this issue?

The hierarchy contains multiple root nodes.

System Response

Because hierarchies can only be displayed with one root node in the
hierarchy simulation, the system only displays the first root node with
its subtree. However, the correctness check is only carried out for the
whole hierarchy.

How to fix this error?

If errors occur in the parts of the hierarchy that are not displayed,
use the preview dialog, in which the system displays the whole
hierarchy in a list, to analyze the error. If you cannot see the error
in this way, individually load the root nodes with their subtrees so
that you can analyze errors in the individual subtrees.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RH094 - The hierarchy contains multiple root node (Only one is displayed) ?

  The SAP error message RH094, which states "The hierarchy contains multiple root nodes (Only one is displayed)," typically occurs in the context of SAP HR (Human Resources) when dealing with organizational structures or reporting hierarchies. This error indicates that the system has detected multiple root nodes in the hierarchy, which is not allowed because a hierarchy should have a single root node.
  Cause:
  
  Multiple Root Nodes: The primary cause of this error is that the hierarchy being processed has more than one root node. In a valid hierarchy, there should only be one top-level node from which all other nodes branch out.
  Incorrect Configuration: This can happen due to incorrect configuration of the organizational structure or hierarchy settings in the SAP system.
  Data Integrity Issues: There may be data integrity issues where nodes are incorrectly linked or not properly defined.
  
  Solution:
  
  Check Hierarchy Structure: Review the hierarchy structure in the SAP system to identify the nodes that are defined as root nodes. Ensure that there is only one root node.
  Adjust Organizational Units: If multiple root nodes are found, you may need to adjust the organizational units or the hierarchy settings to consolidate them under a single root node.
  Use Transaction Codes: Utilize relevant transaction codes such as OOCU (for organizational units) or OOSB (for structure display) to analyze and modify the hierarchy.
  Data Cleanup: If there are inconsistencies in the data, perform a cleanup to ensure that all nodes are correctly linked and that there are no orphan nodes.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing organizational hierarchies.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes related to organizational management, such as PPOME (for displaying and maintaining the organizational plan) and OOCU (for creating and maintaining organizational units).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP Notes can provide additional insights or solutions.
  Testing Changes: After making changes to the hierarchy, test the structure to ensure that the error is resolved and that the hierarchy functions as expected.
  User Permissions: Ensure that you have the necessary permissions to make changes to the organizational structure in SAP.
  
  By following these steps, you should be able to resolve the RH094 error and ensure that your organizational hierarchy is correctly configured.
