  The SAP error message WB2B079 "Combination not allowed" typically occurs in the context of SAP Business Warehouse (BW) or SAP Business Planning and Consolidation (BPC) when there is an issue with the combination of characteristics or key figures in a query or report. This error indicates that the specific combination of data you are trying to use is not valid according to the settings or rules defined in the system.
  Causes:
  
  
  Invalid Characteristic Combinations: The combination of characteristics (dimensions) you are trying to use in your query may not be allowed. For example, certain characteristics may be mutually exclusive or may not be relevant together.
  
  
  Data Model Restrictions: The data model may have restrictions on which key figures can be used together or which characteristics can be combined based on the underlying data structure.
  
  
  Query Design Issues: The query may have been designed in a way that does not allow for the selected combination of data. This could be due to filters, variables, or other settings in the query.
