Hello Pankaja,

Seems like for now custom code is the only option. I was not able to find any out of the box functionality for writing the counts of the total transactions without a custom code.

Here are few strategies for custom code i looked into.

1) In the File Operation , write the messages to a "Temp" File. At a certain time through a task or some other logic read from the temp file and collect all details you need and then write to another File.

2) I yet have to explore this option. At a point in time when you want your file, read from the Enslib.Hl7.Msg and create a file per your needs.

3) Write the live messages to a temp database. Generate necessary file from it when needed. Delete the messages from the DB and copy it to a Archive DB if needed.

4) As live messages are coming write to a Global and then run a task to create messages from the Globals.

Thanks,

Jimmy Christian.

Thank you Marc for the detailed information.

I earlier tried the approach using the Record Mapper but it did not seam feasible in this scenario. 

So i have done is 

Created a CUSTOM operation class which extends Ens.BusinessOperation, EnsLib.HL7.Operation.Standard

It uses the file adapter.

Then I overided the oninit and outputDocument method.

1. The file adapter creates HL7 file as usual
2. I created a new method which calls the override outputDocument method and passes the filename . Then I do a count of segments and create another file into which I copy all the necessary information and delete the file which was originaly created .
3. Above method is called in oninit, so it is triggered on schedule whenever the operation starts. First I check if a file exists, if it does and is not the current file then I call this new method.

Ha ha. Thanks Jeffrey.

Yes the class name User.HL7.Stream seemed like the system defined class.

That is very helpful. I wasnt aware of this class method or class. Thank you for your assistance. I will use it and let you know if  i encounter any issue.

I also tried using another method where i read the stream object using ReadLine.

Then if the string starts with "MSH" OR "FT1" i increment the count.

In that case i have to use the Terminator character as $C(10) or $C(13)

We are not sending telephone number.

Thanks Neerav. That is correct.

Thank you Jenna.

You are absolutely right. I was able to update the DTL code and send a EnsStreamContainer object to the Operation.

It worked perfectly.

Thank you Jeffrey.  This is very helpful.

I didnt realize we can use Source property in the Condition.

Yep !

I did restart the Operation after putting the logic. I had forgotten to set the return status to an error code.

I think E=D works when the %Status has an error code.

Thank you for help.

Thank you Eduard. 

Exactly !

I forgot to set the return status to an error in Catch Block. 

I set to an error code and the Operation is down.

Thank you for help.
