• What is the cause and solution for SAP error message CGPL_BW_INTERFACE002 - Higher-level hierarchy node &1 must be expanded ?

  The SAP error message CGPL_BW_INTERFACE002 indicates that a higher-level hierarchy node must be expanded in the context of a BW (Business Warehouse) interface. This error typically arises when you are trying to process data in a hierarchy structure, and the system requires that certain nodes in the hierarchy be expanded to access the necessary data.
  Cause:
  The error occurs when:
  
  You are attempting to execute a query or data extraction that involves a hierarchy, but the higher-level node (parent node) is not expanded.
  The system needs to access the child nodes of a parent node, but it cannot do so because the parent node is collapsed or not fully expanded in the hierarchy.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Expand the Hierarchy Node:
  
  Navigate to the hierarchy structure in your BW query or report.
  Locate the higher-level node indicated in the error message (denoted as &1).
  Expand this node to ensure that all child nodes are visible and accessible.
  
  
  
  Check Query Settings:
  
  If you are using a BW query, check the settings to ensure that the hierarchy is set to display all levels. You may need to adjust the display settings to allow for the expansion of nodes.
  
  
  
  Data Source Configuration:
  
  Review the configuration of the data source or InfoProvider to ensure that it is set up correctly to handle hierarchies. Make sure that the hierarchy is properly defined and that all necessary nodes are included.
  
  
  
  Re-run the Query:
  
  After expanding the necessary nodes, re-run the query or data extraction process to see if the error persists.
  
  
  
  Consult Documentation:
  
  If the issue continues, refer to SAP documentation or support resources for additional troubleshooting steps specific to your BW version and configuration.
