CGPL_BW_INTERFACE003 - Details

• The SAP error message CGPL_BW_INTERFACE003 indicates that a lower-level hierarchy node must be expanded in the context of a BW (Business Warehouse) interface. This error typically arises when there is an attempt to process a hierarchy node that has child nodes, but those child nodes have not been expanded or processed.
  
  Cause:
  
  Hierarchy Structure: The error usually occurs when the system expects a complete hierarchy structure to be processed, but the lower-level nodes (children) of a hierarchy node are not expanded or included in the data being processed.
  Data Inconsistency: There may be inconsistencies in the data being sent to the BW system, where the hierarchy is not fully represented.
  
  Configuration Issues: There could be issues with the configuration of the hierarchy in the BW system or the source system.
  
  
  Solution:
  
  Expand Hierarchy Nodes: Ensure that all relevant hierarchy nodes are expanded in the data being processed. This may involve modifying the data extraction or transformation
