  The SAP error message CL_RSEXT_TASK_MSG022 indicates that there is no reference characteristic selected for change in a specific context, typically related to the use of the SAP BW (Business Warehouse) or SAP BW/4HANA environment. This error often arises when you are trying to modify or manage characteristics in a data model or InfoObject, and the system expects a reference characteristic to be defined but cannot find one.
  Cause:
  
  Missing Reference Characteristic: The most common cause is that the reference characteristic has not been defined or selected in the context where the change is being attempted.
  Incorrect Configuration: There may be an issue with the configuration of the InfoObject or the data model that is preventing the reference characteristic from being recognized.
  Data Model Issues: If you are working with a composite provider or a similar structure, the underlying data model may not be set up correctly.
