• What is the cause and solution for SAP error message R8374 - A DataSource can only be a leaf in the hierarchy ?

  The SAP error message R8374, "A DataSource can only be a leaf in the hierarchy," typically occurs in the context of SAP BW (Business Warehouse) when dealing with InfoObjects and their hierarchies. This error indicates that the DataSource you are trying to use is not structured correctly within the hierarchy of InfoObjects.
  
  Cause:
  
  Hierarchy Structure: The error arises when a DataSource is defined in a way that it is not a leaf node in the hierarchy. In a hierarchy, leaf nodes are those that do not have any child nodes. If a DataSource is defined as a parent node (i.e., it has child nodes), it cannot be used as a DataSource in certain contexts where only leaf nodes are allowed.
  Incorrect Configuration: The configuration of the InfoObject or the hierarchy might be incorrect, leading to the DataSource being treated as a non-leaf node.
  
  
  Solution:
  
  Check Hierarchy Configuration: Review the hierarchy configuration of the InfoObject associated
