Quelle est la cause de ce problème?

The signature of an BRFplus expression type is defined by an ABAP-OO
interface. The functionality is defined in an ABAP-OO class implementing
that interface. This class also needs to implement the interface
IF_FDT_EXPRESSION.
Optionally there can be further classes defined for an expression type.
These are a query class, a UI class and a data exchange class. For a
detailed description of the functionality provided by these classes,
refer to the BRFplus documentation. If one of the classes is set it
needs to implement a corresponding interface.
These are the following:
The query class needs to implement IF_FDT_OBJECT_QUERY
The UI class needs to implement IF_FDT_UI_DEFINITION
The data exchange class needs to implement IF_FDT_DATA_EXCHANGE_EXTERNAL
