It turns out SAP is leveraging the same concept as BizTalk load balancing concept, with a message server and buntch of application servers. The connection should be setup to the message server instead of the specific application server behind it. This is something new, took me sometime to figure it out. Steps below, Change the […]

The HL7 flat file disassembler use the logic below for body document spec, if party defined, use configured namespace, else use standard HL7 namespace append with #MSH9_1 append with #MSH9_2 append with #MSH12_1 without ‘.’ if MSH12_2 present append it, else append ‘GLO’ if MSH12_3 present append it, else append ‘DEF’ <still not clear> It […]

Problem is if you come up with a custom trigger event within a domain, i.e. ADT_ZZZ, the accelerator requires not only update the MSH schema, but also create the custom schema, i.e. ADT_ZZZ_231_GLO_DEF.xsd. It would be nice if to get rid of this behavior and a single schema handles all custom trigger event within a […]

BTAHL7 Flat File Assemble Pipeline Component – single message a) read value from MSH5.1, 5.2 and 5.3, comnbine them together as destination party b) read message send port name, lookup for its destination party. If there is party configured for that port, override step a) c) if EnablePartialNameResolution is checked, search 5.1+5.2 then try 5.1 […]

So working with HL7 is not that steep learning curve. Problem is there is lot to remember, by that I mean lots of table enumerations, data types etc. A lesson learnt today when I try to create a custom trigger event is, not only you change the namespaces, create a party definition, update the tables […]

DASM can be utilized inside of any custom pipeline, so you are free to create pre- and post-processing on the message as desired. (so we can add custom pipeline component to a pipeline and include HL7DASM, one note on this, MLLP adapter is based on stream, so no seek in PLC designs) If you need […]

The BizTalk Deployment Framework (BTDF) on codeplex makes me both pain and excitement. The pain being lack of information and the poor documentation, the excitement being the power of this tool and its extensibility. I am really struggling learning this tool and up to now I am only getting basic stuffs (i.e. not able to […]

By default, the DBQueryStep only looks for first row, in which case it will cause problem in multiple rows result. I slightly changed the code in BizUnit to make this viable. As a result, stuff all columns to be returned in the <rows> secion, i.e.      <Rows>        <Columns>          <TotalRecordCount>1</TotalRecordCount>          <Direction>IN</Direction>          <TotalRecordCount>1</TotalRecordCount>          <Direction>OUT</Direction>        </Columns>      </Rows> Updated […]

Wrapped up the development for this interface today, it is nothing challenging, which brings me enough time for the testing piece. So this is actually the first time that I did unit testing, well, I did read a lot, but yes, this is the first time I did it. I have to say NUnit is […]
