• What is the cause and solution for SAP error message RSR_TRANS020 - TAG 'HIERARCHY' is not allowed in structures ?

  The SAP error message RSR_TRANS020 indicates that there is an issue with the use of a hierarchy in a structure within a query or report. Specifically, the error message states that the tag 'HIERARCHY' is not allowed in structures, which typically means that the system is encountering a hierarchy where it is not expected or permitted.
  Cause:
  
  Incorrect Use of Hierarchies: The error often arises when a hierarchy is incorrectly included in a structure or when a query is trying to use a hierarchy in a context that does not support it.
  Query Design Issues: If you are designing a query in SAP BW (Business Warehouse) and you have included a characteristic that is defined as a hierarchy in a structure, this can lead to the error.
  Incompatibility with Data Sources: The data source or InfoProvider you are using may not support hierarchies in the way you are trying to implement them.
  
  Solution:
  
  Review Query Design: Check the query design in the BEx Query Designer. Ensure that you are not using a hierarchy in a structure where it is not allowed. If you need to use a hierarchy, consider using it in a different context, such as in a free characteristic or in a different part of the query.
  Modify the Structure: If the structure is defined in a way that includes a hierarchy, you may need to modify it to exclude the hierarchy or to use a different characteristic that does not involve a hierarchy.
  Check InfoObjects: Ensure that the InfoObjects used in the query are compatible with the structure and do not include hierarchies where they are not allowed.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on using hierarchies in queries and structures.
  
  Related Information:
