Service operation support for EDISeparator adapter

Hello Experts,

I am configuring the Sender EDISeperator adapter and the Sender service interface assigned to this EDISeperator adapter has multiple service operations attached to it.

An example is shown below :

I am getting the below error :

Questions:

1.Can anybody help me to resolve this error.

2. Does the EDISeparator adapter support Stateless interface pattern (i.e Service interface with multiple operations)

3.Is it mandatory to have the message type name (See "Name" column above) as ORDERS96A..i.e can we add suffixes to it like ORDERS96A_MT. I have noticed that if we add these suffixes the EDISeparator adapter throws an error. Is this understanding correct.

Thanks
