Quelle est la cause de ce problème?

Extension &v1& was used in Release 3.0/3.1 with several basic types.
For Release 4.0, however, an extension can only be linked with one
basic type, in order to simplify the complexity of the dependencies.

Réponse du système

Please note that IDoc processing is not impaired at first. Problems can
arise if changes are made to extension &v1& or one of the basic types
concerned.
The tests regarding segment relationships are only executed with the
basic type assigned. The other basic types (also currently in use) are
ignored.

Comment corriger cette erreur?

If you plan to process extension &v1& further, you should proceed as
follows:
create several identical copies of your extension
assign one of the basic types used to each of these copies
modify the partner profiles and customer exits that have used the old
extension &v1& until now, and replace the name of the extension with
that of one of your copies.
You should now have created a number of independent extensions, each of
which is linked with a single basic type.
