HL7 interaction without PI

Hello everyone,

We need to estimate and define interaction with LIS and RIS systems by means of standard HL7 messages (ADT, ORU, ORM, etc) and TCP/IP protocol. SAP doesn't support this functionality in an easy way as far as I know. It will only drop a file and then per inbound communication you have to use BAPIs.

Is there any way to easily configure SAP to send and receive HL7 messages over TCP/IP? We will use the most common ones in version 2.X. I can't find an easy solution to this scenario. The system is 6.04 ECC.

Is it really necessary to have a middle ware to accomplish this functionality?

Any help will be appreciated (example files, diagrams, specifications, etc).

Regards.

Damián.
