Screen shot of error message.png


This error is being caused because of the usage of both the [Relation] as well as the [Reference] attributes in common. If in a scenario,  where the field is also being referred by another extension business object (XBO), the deletion of the field fails leading to this error message.


The change of a Relation's target attribute is an incompatible change. If the Relation attribute is only being added in current version then the field is deleted and regenerated.

The two annotations will work separately, but the usage of both the [Relation] and the [Reference] attributes in tandem is not supported.
