  The SAP error message RSMPC187, which states "You can only select a maximum of three selection fields," typically occurs in the context of using the SAP BW (Business Warehouse) or SAP BI (Business Intelligence) reporting tools. This error indicates that the user has attempted to select more than the allowed number of selection fields when executing a query or report.
  Cause:
  The primary cause of this error is that the query or report you are trying to execute has a limitation on the number of selection fields that can be used simultaneously. This limitation is often set to ensure optimal performance and to avoid overly complex queries that could lead to long processing times or system performance issues.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Reduce Selection Fields: Review the selection fields you have chosen and reduce the number to three or fewer. This may involve deselecting some fields that are not critical for your analysis.
  
  
  Combine Filters: If possible, combine multiple criteria into a single selection field. For example, if you are filtering by multiple values in a single field, consider using a range or a list of values.
  
  
  Use Hierarchies: If applicable, use hierarchies or aggregated fields that can represent multiple values within a single selection field.
  
  
  Check Query Design: If you are the designer of the query, check the query settings in the Query Designer. You may need to adjust the settings to allow for more selection fields, but be cautious as this may impact performance.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on selection field limitations for the particular version of SAP BW or BI you are using.
  
  
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
