need help on receiver determination

Hi all,

I am using Database lookup (user define function) to get some fields based on the input request from the sender(WebService)

This is Synchronous scenario from WebService to RFC.

Now my problem is, I need to determine the particular receiver from the 4 receivers based on the ID field which I am getting from the external database via Database lookup.

Each receiver has same message mapping

Can anybody please suggest me how to do this?

Do I've to create 4 mappings, 4 CC and 4 Interface Determination?

Regards

Chintan
