• What is the cause and solution for SAP error message 28054 - &1 is not a multiple-value characteristic ?

  The SAP error message "28054 &1 is not a multiple-value characteristic" typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when dealing with characteristics in InfoObjects. This error indicates that the characteristic you are trying to use is not defined as a multiple-value characteristic, which means it cannot hold multiple values for a single record.
  Cause:
  
  Characteristic Definition: The characteristic in question is defined as a single-value characteristic in the InfoObject settings. This means it can only hold one value at a time.
  Data Model Misconfiguration: The data model or the query you are trying to execute expects a multiple-value characteristic, but the characteristic is not configured to support that.
  Query Design: If you are designing a query in BEx Query Designer or similar tools, you might have inadvertently set a filter or selection that expects multiple values for a characteristic that is not configured as such.
  
  Solution:
  
  
  Check Characteristic Settings:
  
  Go to the InfoObject maintenance (transaction code RSD1).
  Find the characteristic that is causing the error.
  Check the settings to see if it is defined as a single-value characteristic. If it needs to support multiple values, you may need to change its settings.
  
  
  
  Modify Query or Data Model:
  
  If you are working with a query, review the filters and selections applied to the characteristic. Ensure that you are not trying to apply multiple values to a characteristic that is not configured for it.
  If necessary, redesign the query to accommodate the single-value characteristic.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for more information on how to configure characteristics and the implications of single vs. multiple-value characteristics.
  
  
  
  Testing:
  
  After making changes, test the query or data model again to ensure that the error is resolved.
