Today, I saw a send port that had a filter such as BTS.Operation == Send204External. I looked at the orchestrations that I thought were involved in this application/project, but couldn’t find that operation name in any of the orchestration send ports.

There are two approaches to doing the xref:
1) Scanning all the code. I use Total Commander which has a great built-in utility to scan files with a mask (such as *.odx) for a given term (Send204External). But this assumes I have all the code on my disk (from our source code repository), and it doesn’t always run quickly.
2) Run a SQL query against the BizTalk SQL database.

In BizTalk, each orchestration logical (internal) SendPort can have one or more operations.

<pre>
using BizTalkMgmtDB 
select 
       app.nvcName as 'Application', 
       pto.nvcName as 'Operation', 
       pt.nvcName as 'PortType',
       op.nvcName as 'Orch-PortName',
       ass.nvcName as 'Assembly_Name'
         from bts_porttype_operation pto 
   inner join bts_porttype pt on pto.nPortTypeID = pt.nID 
   inner join bts_orchestration_port op on op.nPortTypeID = pt.nID 
   inner join bts_assembly ass on pt.nAssemblyID = ass.nID 
   inner join bts_application app on ass.nApplicationID = app.nID 
where pto.nvcName = 'Send204External'
