• What is the cause and solution for SAP error message HR_BW_PY99020 - Mode &1 is not supported by DataSource ?

  The SAP error message HR_BW_PY99020 indicates that a specific mode (denoted as &1) is not supported by the DataSource you are trying to use in the context of SAP BW (Business Warehouse) and HR (Human Resources) data extraction. This error typically arises when there is a mismatch between the mode of operation you are attempting to use and the capabilities of the DataSource.
  Cause:
  
  Unsupported Mode: The DataSource you are using may not support the mode you are trying to execute (e.g., delta load, full load, etc.).
  Configuration Issues: There may be configuration issues in the DataSource settings or in the BW extraction process.
  Version Compatibility: The version of the DataSource may not be compatible with the BW version you are using.
  DataSource Activation: The DataSource may not be properly activated or may not have been updated to reflect recent changes.
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP system and check its configuration. Ensure that the mode you are trying to use is supported.
  You can do this by navigating to the DataSource in transaction RSA1 (Data Warehousing Workbench) and reviewing its settings.
  
  
  
  Use Supported Mode:
  
  If the mode you are trying to use is not supported, switch to a mode that is supported by the DataSource. For example, if you are trying to perform a delta load and it is not supported, consider using a full load instead.
  
  
  
  Update DataSource:
  
  If there have been recent changes to the DataSource, ensure that it is activated. You can do this in transaction RSA1 by selecting the DataSource and choosing the activation option.
