SAP Enterprise Services Doubts

Hi all,

We are looking at some of the enterprise services provided in SAP ECC at link below:

We have some doubts regarding the was these services are populated for outbound processing and how the errors are handled in inbound processing. We would be very grateful if we could get your feedback.

Regarding the oubound services, are they created by configuration or just a BADI is provided to implement the logic to retrieve the data and fill the outbound proxy in? In case the service is created automatically by just customazing, is there any documentation of the relevant customazing steps to be carried out?

Regarding the inbound services, can all of them make use of the FEH (Forward Error Handling) Framework for handling the errors in the posting?

Many thanks for your information,

Kind regards.
