WFE_REQUEST_CRM203 - Details

• The SAP error message:
  WFE_REQUEST_CRM203 & is not a data element. At present, only data elements are supported.
  
  Cause:
  This error typically occurs during workflow or ABAP development when a field or parameter is expected to be a data element, but the object referenced (in this case, CRM203 or a similar identifier) is not a data element. Instead, it might be a domain, structure, table type, or some other dictionary object.
  In SAP, certain workflow or function module interfaces require parameters to be defined as data elements because data elements carry semantic information and are used for consistent typing and UI generation. If a parameter or field is defined directly as a domain or a structure, or if the system cannot resolve it to a data element, this error is raised.
  When does it occur?
  
  When defining workflow container elements or binding parameters.
  When creating or modifying function module interfaces or BAdI methods.
  When using certain tools or
