• What is the cause and solution for SAP error message FCOM_MASTERDATA034 - Cannot activate more than one hierarchy version at a time ?

  The SAP error message FCOM_MASTERDATA034 indicates that you are trying to activate more than one hierarchy version simultaneously in the Financial Accounting (FI) or Controlling (CO) module. This is not allowed in SAP, as the system can only handle one active version of a hierarchy at a time.
  
  Cause:
  The error typically occurs when:
  
  You attempt to activate a new hierarchy version while another version is already active.
  There may be a misunderstanding of the hierarchy management process, leading to multiple activations being attempted.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Active Hierarchy Versions:
  
  Go to the relevant transaction (e.g., transaction code KCH1 for controlling hierarchies) to check which hierarchy versions are currently active.
  Identify the active version that is causing the conflict.
  
  
  
  Deactivate Existing Hierarchy:
  
  If you need to activate a new version, you must first deactivate the currently active version.
  Use the appropriate transaction (e.g., KCH2 for deactivating a controlling hierarchy) to deactivate the existing version.
