No logicalport provided for &1. PI as default runtime is disabled.

What causes this issue?

PI is not the default for outbound consumer proxy call if no logical
port is used.
There is no default logical port defined for the consumer proxy &V1& and
the proxy is instantiated without an explicit logical port name.

How to fix this error?

If PI should process the outbound call there are following options:
Create a PI logical port or choose an existing PI logical port in
SOAManager. Define it as default logical port.
Adapt the coding and instantiate the consumer proxy &V1& with the name
of a PI logical port.
Enable PI as the default runtime (see below).
If Web Service should process the outbound call there are two options:
Create a Web Service logical port or choose an existing in SOAManager.
Define it as default logical port.
Adapt the coding and instantiate the consumer proxy &V1& with the name
of a Web Service logical port.
