Diagnosis
You set a structure as a data dictionary reference. However, from thepoint of view of generic attributes, this makes no sense, as thestructure cannot be used internally.

System Response
Internally, the system uses the reference to the field HRT1222-LOW. Ittherefore treats the attribute as if it were untyped.

Procedure
To define the attribute correctly, use a field from a flat structure.
You can only define invisible attributes in this way.
