• What is the cause and solution for SAP error message RSO_RES_QMSGS126 - Hierarchy not supported for target object. &1 ?

  The SAP error message RSO_RES_QMSGS126 indicates that a hierarchy is not supported for the target object specified in the error message. This typically occurs in the context of SAP BW (Business Warehouse) when working with queries, InfoObjects, or data models that involve hierarchies.
  Cause:
  
  Hierarchy Not Defined: The target object (e.g., InfoObject, query) does not have a hierarchy defined or the hierarchy is not activated.
  Incompatible Hierarchy: The hierarchy being used is not compatible with the target object. For example, if the target object is a characteristic that does not support hierarchies.
  Incorrect Query Design: The query might be designed in a way that it expects a hierarchy, but the underlying data model does not support it.
  Transport Issues: If the object was transported from one system to another, the hierarchy might not have been transported correctly.
  
  Solution:
  
  Check Hierarchy Definition: Ensure that the hierarchy is defined and activated for the target InfoObject. You can do this by navigating to the InfoObject maintenance in the SAP BW system.
  Review Query Design: If you are working with a query, check the query design to ensure that it is correctly set up to use the hierarchy. Make sure that the characteristic used in the query supports hierarchies.
  Validate Compatibility: Ensure that the hierarchy you are trying to use is compatible with the target object. You may need to adjust the hierarchy or the target object accordingly.
  Transport Check: If the issue arose after a transport, verify that all necessary objects, including hierarchies, were transported correctly. You may need to re-transport the hierarchy or check for missing dependencies.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW you are using for any known issues or additional configuration steps.
