Explanation
Search help parameters must be assigned to a data element. The data element provides the parameter's definition including its semantic properties (description) and references a domain for technical attributes (data type, length). This ensures the search help parameter knows what type of data to handle and how to describe it to users.
AI explanation
Every search help parameter must be assigned to a Data Element, because the Data Element is what links the parameter to its domain, value range, and field labels/documentation. Without a Data Element, the search help wouldn't know what kind of data or value help to present for that parameter.
