• What is the cause and solution for SAP error message RTCMMD237 - CDT update only permitted for non-scheduled hierarchies ?

  The SAP error message RTCMMD237 indicates that a change data transfer (CDT) update is being attempted on a scheduled hierarchy, which is not permitted. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with master data or hierarchies.
  Cause:
  The error occurs because the system is trying to perform an update on a hierarchy that is defined as "scheduled." Scheduled hierarchies are typically used for time-dependent data and are not meant to be updated through the CDT process. The CDT process is designed for non-scheduled hierarchies, which can be updated freely without time constraints.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Check Hierarchy Type: Verify if the hierarchy you are trying to update is indeed a scheduled hierarchy. If it is, you will need to either:
  
  Change the hierarchy type to a non-scheduled hierarchy if that fits your business requirements.
  Use a different method to update the scheduled hierarchy, such as using the appropriate transaction or process designed for scheduled hierarchies.
  
  
  
  Update Method: If you need to update a scheduled hierarchy, you may need to use the specific transaction codes or processes that are designed for handling scheduled hierarchies. This might involve using the SAP GUI or specific BW transactions.
  
  
  Review Documentation: Consult the SAP documentation or help resources for more details on how to manage hierarchies and the limitations of CDT updates. This can provide insights into best practices and alternative methods for updating your data.
  
  
  Consult with SAP Support: If you are unsure about the hierarchy settings or how to proceed, consider reaching out to SAP support or your internal SAP team for assistance. They can provide guidance based on your specific system configuration and business requirements.
  
  
  Related Information:
  
  Hierarchy Types: Understand the difference between scheduled and non-scheduled hierarchies in SAP BW. Scheduled hierarchies are often used for time-dependent data, while non-scheduled hierarchies are more flexible for updates.
  SAP Notes: Check for any relevant SAP Notes that might address this error or provide additional context on handling hierarchy updates.
  Transaction Codes: Familiarize yourself with transaction codes related to hierarchy management in SAP BW, such as RSD1 for InfoObjects and RSH1 for managing hierarchies.
  
  By following these steps, you should be able to address the RTCMMD237 error and successfully manage your hierarchy updates in SAP.
