• What is the cause and solution for SAP error message RSRTS_CDS201 - Parameter &1: value help ignored. Value help field not specified. ?

  The SAP error message RSRTS_CDS201 with the description "Parameter &1: value help ignored. Value help field not specified." typically occurs in the context of using SAP BW (Business Warehouse) or SAP HANA when working with CDS (Core Data Services) views or queries. This error indicates that there is an issue with the value help configuration for a parameter in a query or a report.
  Cause:
  The error is caused by the absence of a specified value help field for a parameter in a CDS view or query. Value help is used to provide users with a list of possible values for a parameter, and if it is not defined correctly, the system cannot provide the necessary assistance.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Parameter Definition:
  
  Go to the CDS view or query definition where the error is occurring.
  Ensure that the parameter in question has a value help field defined. This is typically done in the parameter declaration section of the CDS view.
  
  
  
  Define Value Help:
  
  If the value help field is not specified, you need to define it. This can be done by adding a @Consumption.valueHelp annotation to the parameter in the CDS view. For example:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @AccessControl.authorizationCheck: #CHECK
  define view Z_MY_CDS_VIEW
  as select from my_table
  {
    key field1,
    field2,
    ...
    @Consumption.valueHelp: 'my_value_help'
    parameter my_parameter : my_data_type
  }
  
  
  
  
  Check the Value Help Definition:
  
  Ensure that the value help itself is correctly defined and points to a valid data source. This could be another CDS view or a table that contains the values you want to provide as help.
  
  
  
  Activate the CDS View:
  
  After making changes, make sure to activate the CDS view or query to apply the changes.
  
  
  
  Test the Query:
  
  Run the query again to see if the error persists. If the value help is correctly defined, the error should no longer appear.
