Is it mandatory to use a Fault Message Type.

Hi all

I am currently doing a Soap-Proxy synchronous scenario,where by sending an employee id through webservice to SAP ECC ,employee details will be retreived from ECC as a response.

In this scenario, is it necessary to specify the Fault Message Type in the outbound and inbound synchronous Message interfaces and do the corresponding message mapping for Fault message types.

Asvance Thanks,

Ram.
