Using oData Channel (minimal gateway) how do I expose FunctionImports in the metadata document?
My understanding is that a FunctionImport is used to support 'actions' or 'operations' that don't map to collections, and allow clients to use OData documents to be used to perform some (arbitrary) backend operation,
But I have no idea how to tie the backend BAPI/RFM to either the metadata description or the runtime behaviour.
I guess this is documented someplace, but I have not found out where.
Anyone point me in the right direction?
