• What is the cause and solution for SAP error message RSZA018 - Query structure is not a key figure structure ?

  The SAP error message RSZA018, which states "Query structure is not a key figure structure," typically occurs in the context of SAP BW (Business Warehouse) when working with queries in the BEx (Business Explorer) Query Designer. This error indicates that the structure you are trying to use in your query is not defined as a key figure structure, which is necessary for certain types of calculations or aggregations.
  Cause:
  
  Incorrect Structure Type: The structure you are trying to use in your query is not defined as a key figure structure. Key figures are numerical values that can be aggregated, while characteristics are descriptive attributes.
  Query Design Issues: The query may have been designed incorrectly, where a characteristic structure is mistakenly used in a context that requires a key figure structure.
  Data Source Configuration: The underlying data source (InfoProvider) may not be set up correctly to support key figures.
  
  Solution:
  
  Check Structure Definition: Verify that the structure you are using in your query is indeed a key figure structure. You can do this by checking the properties of the structure in the InfoObject or InfoProvider.
  Modify Query Design: If you have mistakenly added a characteristic structure where a key figure structure is required, you will need to adjust your query design. Ensure that you are using the correct key figures in your query.
  Use Key Figures: Make sure to include only key figures in the relevant sections of your query (e.g., in the rows or columns where aggregations are expected).
  Review Data Source: Check the configuration of the data source (e.g., InfoCube, DSO) to ensure that it is set up to provide key figures correctly.
  Recreate the Query: If the issue persists, consider recreating the query from scratch, ensuring that you only include valid key figures.
  
  Related Information:
  
  Key Figures vs. Characteristics: In SAP BW, key figures are numerical data that can be aggregated (e.g., sales amount, quantity sold), while characteristics are descriptive attributes (e.g., product name, customer ID).
  BEx Query Designer: Familiarize yourself with the BEx Query Designer tool, which allows you to create and modify queries. Understanding how to properly use key figures and characteristics is crucial.
  SAP Notes and Documentation: Check SAP Notes for any specific patches or updates related to this error. SAP's official documentation can also provide insights into query design best practices.
  
  If you continue to experience issues, consider reaching out to your SAP BW administrator or consulting SAP support for further assistance.
