• What is the cause and solution for SAP error message CMCB_MSG045 - Multiple roots for org hierarchy &1 is not allowed ?

  The SAP error message CMCB_MSG045 indicates that there are multiple root nodes in the organizational hierarchy for a specified organizational unit (denoted by &1). This situation is not allowed in SAP, as an organizational hierarchy should have a single root node to maintain a clear structure.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Data Integrity Issues: There may be inconsistencies in the organizational structure data, leading to multiple entries being treated as root nodes.
  Incorrect Configuration: The configuration of the organizational hierarchy may not have been set up correctly, allowing for multiple roots.
  Data Migration Issues: If data was migrated from another system, it may have resulted in duplicate or conflicting entries.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Organizational Structure:
  
  Use transaction codes like PPOME (for Organizational Management) or PPOSE to visualize the organizational structure.
  Identify the nodes that are being treated as root nodes.
  
  
  
  Identify and Remove Duplicates:
  
  Look for any duplicate entries that may be causing the issue. Ensure that there is only one root node for the hierarchy.
  If you find multiple root nodes, determine which one should be the actual root and remove or reassign the others.
  
  
  
  Correct Configuration:
  
  Review the configuration settings for the organizational hierarchy. Ensure that the settings allow for a single root node.
  If necessary, consult with your SAP Basis or configuration team to ensure that the organizational management settings are correctly configured.
  
  
  
  Data Consistency Checks:
  
  Run consistency checks on the organizational data to identify any other potential issues that may not be immediately visible.
  Use transaction OM01 to check for inconsistencies in the organizational management data.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to organizational management for additional guidance on resolving hierarchy issues.
  
  
  
  Testing:
  
  After making changes, test the organizational hierarchy to ensure that the error no longer occurs and that the structure is functioning as expected.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as PPOME, PPOSE, and OM01 for managing and viewing organizational structures.
  SAP Notes: Check SAP Notes for any known issues or patches related to organizational management and hierarchy errors.
  User Roles and Authorizations: Ensure that you have the necessary authorizations to make changes to the organizational structure.
  
  By following these steps, you should be able to resolve the CMCB_MSG045 error and maintain a valid organizational hierarchy in your SAP system.
