Interfaces for RFQ
we are working with a customer who runs an external system to handle "Requests for Quotations" and he want to integrate this with his SAP system on 46c.
The scenario for this integration will be that, someone in SAP will create the RfQ referencing a requisition via ME41, adds all needed additional data like material numbers, quantities and delivery dates. After the RfQ is saved, all available informations of the RfQ has be be transfered to the external system. It should also be possible to update the RfQ on the SAP side and forward the updates to the external system.
The results from the RfQ of the external system should be transfered back to the SAP system (ME47 including price quote, attaching documents to the item).
Back to my question, we are looking for the correct API's (IDOC or BAPI/RFC) to support the mentioned scenario?
