• What is the cause and solution for SAP error message RSRTS_CDS001 - Right side of comparison expression must be literal value ?

  The SAP error message RSRTS_CDS001 with the description "Right side of comparison expression must be literal value" typically occurs in the context of SAP BW (Business Warehouse) when working with Composite Providers or when using CDS (Core Data Services) views. This error indicates that there is an issue with a comparison expression in a query or a filter where the right side of the comparison is expected to be a literal value, but it is not.
  Cause:
  The error is usually caused by one of the following scenarios:
  
  Dynamic Values: The right side of a comparison expression is using a variable or a field reference instead of a static value. For example, if you have a filter condition like field = variable, it will trigger this error because variable is not a literal value.
  Incorrect Syntax: There may be a syntax error in the query or filter definition that leads to the system interpreting the expression incorrectly.
  Data Type Mismatch: The data type of the value being compared may not match the expected data type of the field, leading to confusion in the comparison.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Use Literal Values: Ensure that the right side of your comparison expression uses a literal value. For example, instead of using a variable, use a specific value like field = 'SomeValue'.
  
  
  Check Query Filters: Review the filters applied in your query or Composite Provider. Make sure that all comparisons are made with literal values.
  
  
  Review Syntax: Double-check the syntax of your query or filter definition. Ensure that all expressions are correctly formed and that there are no typos or misplaced operators.
  
  
  Data Type Consistency: Ensure that the data types of the fields being compared are consistent. If you are comparing a string field, make sure the literal value is also a string.
  
  
  Debugging: If you are unsure where the issue lies, you can debug the query or use transaction codes like RSRT to analyze the query execution and identify the problematic part.
