In BizTalk 2004 it's possible to connect just one Receive Port an SAP enviroment.

This can be a limitation when i want to receive many kinds Idoc (p.es. DELVRY02, ZOIFSEDE01, ... ).

For solve this problem i have create a simple orchestration that receive an inbound document very simple: the figure Inbound_Message explain that.

 

This schema have an simple row that load all Idoc Received from SAP.

The orchestration give inbound document to an external assembly that read the Idoc and in the position 39 on the first row there is tha Idoc Family name. Depends this name the assembly can direct the entire Idoc in the right position (p.es. Folder, HTTP, ... ). The figure Orchestration_Idoc_Message explain that. I conseil of use a configuration file XML where put the rule of binding. P.es. the Idoc DELVRY02 must go in folder D:\DELVRY02, the Idoc ZOIFSEDE01 must go to folder D:\ZOIFSEDE01 and go on.

 

This is a very simple solution for solve the problem with unique Receive Port in binding with SAP enviroment.
