How To Fix SIW332 - Proxy has not yet been generated or proxy class is not active

SAP Error Message - Details

• Message type: E = Error

• Message class: SIW - Service Implementation Workbench

• Message number: 332

• Message text: Proxy has not yet been generated or proxy class is not active

What causes this issue?

SIW tries to retrieve additional information about service proxies in
order to process a request. The information available however does not
point to a valid proxy. This may either mean that the proxy you
requested has not been generated or activated or it can mean that the
values available do not point to a valid proxy anyway.
An example for the latter is that you specified "Outbound" for the
direction of the proxy although the proxy in question is an inbound one.

System Response

No information can be retrieved and the process stops.

How to fix this error?

Please verify that the proxies you need for the project have been
generated and activated. If this is the case please double check if all
given values are valid.
