Diagnosis
The two partners of the value assignment in a binding definition mustbe defined by identical data types or at least compatibledata types.
Data types which are expressed via a field reference are"compatible" if the source element is shorter than the target elementfor the same data type.
Data types which are expressed via an object reference arecompatible:

• if no object type is explicitly specified for the target element

(assignment: specified object reference ==> unspecified objectreference)

• if the source element references a subtype of the object type which is
referenced by the target element
(assignment: object reference subtype ==> object reference supertype)

Procedure
You should use F4 input help for the binding definition.
You should only select container elements which F4 input help showshave the following characteristics: "Data type identical" or"Compatible".
