SAP Error Message - Details

• Message type: E = Error

• Message class: CFD_REGISTRY_CHECK - Custom Fields: Messages for Registry Check

• Message number: 368

• Message text: Reuse of data Type &1 not allowed

What causes this issue?

Reuse of proxy data types in SOAP messages is only allowed under certain
circumstances. Data type <(>&<)>1 is also used in operation <(>&<)>3 of
service interface <(>&<)>2. A combination of proxy data type reuse and
multiple registrations in different operations or service interfaces is
not allowed.

System Response

Registration of proxy data type <(>&<)>1 for extensibility is not
allowed for the current operation.

How to fix this error?

Ensure that you use different proxy data types in each operation. Don't
make use of the data type reuse feature if you want to register the same
proxy data type in different operations and as well in different
business contexts. Further you can open an incident to component
BC-SRV-APS-EXT-FLD to double check this restriction for your use case.
