IDE refuses the import of two diffeernt service interfaces based on the samy type
HINTS
If you want to import a service interface in SAP NetWeaver BPM on 7.11 that is based on the same type (in terms of namespace + name) than another service that is already part of the process model it needs to be ensured that the old and the new type are 100% equal. In the very first release this is also true for the documentation of both types (e.g. xsd:annotation) as the importer is very strict. Otherwise the IDE will refuse to import the second service interface.
First solution would be to use 100% equal types. If that is too much effort renaming the second type (or its namespace) might be an alternative.
