• What is the cause and solution for SAP error message R8459 - No DataSource with HIER type exists in source system -> 329 ?

  The SAP error message R8459 indicates that there is no DataSource with a HIER (Hierarchy) type available in the source system for the specified object. This error typically occurs when you are trying to extract data from a source system that is expected to have a hierarchy structure, but the required DataSource is not defined or available.
  Cause:
  
  Missing DataSource: The DataSource that is supposed to provide the hierarchy data is not created or activated in the source system.
  Incorrect Configuration: The DataSource might be incorrectly configured or not linked properly to the relevant InfoObject in the target system.
  Transport Issues: If the DataSource was recently transported from another system, it may not have been properly activated in the target system.
  Source System Issues: The source system may not have the necessary hierarchy data available or may not be set up to provide it.
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the source system and check if the DataSource exists. You can do this by navigating to the DataSource maintenance transaction (e.g., RSA1 in the source system).
  Ensure that the DataSource is of the correct type (HIER) and is activated.
  
  
  
  Create or Activate DataSource:
  
  If the DataSource does not exist, you may need to create it. This can involve defining the hierarchy structure and ensuring it is linked to the appropriate InfoObject.
  If it exists but is not activated, activate it in the source system.
  
  
  
  Check for Transport Issues:
  
  If the DataSource was recently transported, ensure that all necessary objects were included in the transport request and that they were successfully imported into the target system.
  
  
  
  Review Source System Settings:
  
  Ensure that the source system is configured to provide the necessary hierarchy data. This may involve checking the settings in the source system's data model.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource you are working with for any additional configuration steps or requirements.
  
  
  
  Check for Updates:
  
  Ensure that both the source and target systems are updated with the latest patches and notes from SAP, as there may be fixes or enhancements related to DataSources.
