• What is the cause and solution for SAP error message RSRTS_CDS149 - Too many arguments (at least &3) for BW operator &1 (up to &2 operands) ?

  The SAP error message RSRTS_CDS149 indicates that there is an issue with the number of arguments being passed to a BW (Business Warehouse) operator in a query or calculation view. Specifically, the error states that there are too many arguments provided for the operator, exceeding the allowed limit.
  Cause:
  This error typically occurs when:
  
  Exceeding Operand Limit: The BW operator you are using has a defined limit on the number of operands it can accept. If you provide more operands than allowed, this error will be triggered.
  Incorrect Query Design: The design of the query or calculation view may be incorrect, leading to an unintended increase in the number of arguments.
  Complex Calculations: If you are using complex calculations or combining multiple operators, it may inadvertently lead to exceeding the operand limit.
  
  Solution:
  To resolve the RSRTS_CDS149 error, you can take the following steps:
  
  
  Review the Operator Documentation: Check the documentation for the specific BW operator you are using to understand its operand limits. Ensure that you are not exceeding these limits.
  
  
  Simplify the Query: If possible, simplify your query or calculation view. Break down complex calculations into smaller, manageable parts that do not exceed the operand limit.
  
  
  Reduce the Number of Arguments: Identify and remove any unnecessary arguments or operands from your query. Ensure that you are only using the required number of operands.
  
  
  Use Alternative Operators: If the operator you are using cannot accommodate your needs due to operand limits, consider using alternative operators or functions that can achieve the same result without exceeding the limits.
  
  
  Test Incrementally: If you are making changes to the query, test it incrementally to identify the specific part that causes the error. This can help you isolate the issue more effectively.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or updates that may address this specific error or provide additional guidance.
  
  
  Related Information:
  
  SAP BW Documentation: Refer to the official SAP BW documentation for detailed information on operators and their limitations.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Performance Considerations: Be mindful of performance implications when designing queries, as overly complex queries can lead to performance degradation in addition to errors.
  
  By following these steps, you should be able to identify the cause of the RSRTS_CDS149 error and implement a solution to resolve it.
