go to post Marc Mundt · Apr 13, 2022 Just to add a bit of context to the above:An example use case where you would want to return the operation's response back to the service would be in an HL7 integration where, instead of having the service generate an ACK to return to the upstream sending system, we want to return the ACK or NAK that we got back from the downstream receiving system.
go to post Marc Mundt · Apr 13, 2022 What Response From does is control which responses from a call to an operation (or another component) are returned to the business service that called the router. By default the router won't return the response to the service, but setting Response From will enable responses to be returned from specific operations (or * for all operations). This is how you can control which response gets sent back to the service in a case when a router calls multiple operations. If multiple responses match the Response From setting, then only the first response will be returned to the service. Response Target Config Names allows you to specify additional components (beyond the service that called the router) that should receive a copy of the response that came back from the operation. So you could send a copy of an ACK or other response to another operation for some reason. All of this is probably moot, because I'm guessing your service doesn't need to receive a response. In terms of the NULL responses, these shouldn't become orphans -- the fact that they appear in the message trace tells us that the production knows which session they belong to so they should get deleted along with the rest of the session.
go to post Marc Mundt · Apr 12, 2022 Absolutely. You can do this with two assign actions: First assign action moves the stream pointer to the end of the stream content: The second assign action writes our new content to the end of the stream: And an extra note of explanation: what we're actually doing with these assigns is calling a method in the request class, which returns a status code, and assigning that status code to a temporary variable. It would be best to check this status code to see if there was an error, but I haven't added that here to keep things simple.
go to post Marc Mundt · Apr 11, 2022 The PassthroughService will place the file contents in a stream, insert that stream into an Ens.StreamContainer object and send that to the Business Process. So Ens.StreamContainer, and the stream that it contains, is what your Business Process code will need to work with. See this page for information on working with streams. Streams are different than simple strings and require using stream-specific methods for reading and writing content into the stream. Unless you have a specific reason to write your business process in ObjectScript, I would recommend that you create a BPL-based business process using the visual BPL editor. There are more details here on creating business processes.
go to post Marc Mundt · Apr 11, 2022 A few questions that will help us to understand better:- Which business service are you using? Is it custom or out-of-the-box?- If the service is custom, what type of object is it sending to the Business Process?- What type of Business Process are you using? Is it BPL, ObjectScript, or a router using routing rules?
go to post Marc Mundt · Apr 11, 2022 Since you don't need to modify the request/response maybe pass-through services and operations will meet your needs?
go to post Marc Mundt · Apr 5, 2022 This section in the docs discusses business processes and routers. You could use either one -- routing rules tend to be faster/easier to create. Basically, your business process or routing rule would create a notification message and send it to a business operation. The process/router could construct the notification message directly or could call a data transformation that would create the notification message. The operation would send the notification to an external system. One example would be to use an email operation to send the notification to an email server.

go to post Marc Mundt · Apr 5, 2022 Can you elaborate on the limitations you see in DocumentType that are leading you to think about using Custom Pairs? DocumentType is of type HS.SDA3.CodeTableDetail.DocumentType, which can store a code, description, and the code system. Seems like that's what you need, and it already maps to DocumentReference:type in FHIR.

go to post Marc Mundt · Mar 29, 2022 calling Method from ClassMethod This is the problem. A Method needs to be called in the context of an instantiated object. A ClassMethod by definition isn't associated with an instantiated object. If it's necessary to do it this way, your ClassMethod could use %New() to instantiate an object and then call the Method on that object: set myObj = ##class(My.Object.Class).%New() set tSC=myObj.myMethod() But, it looks like you're working with a Business Service class. For that, it isn't enough to simply use %New(). You need to use Ens.Director::CreateBusinessService to instantiate the object before calling the Method. https://docs.intersystems.com/irisforhealth20212/csp/docbook/DocBook.UI....

go to post Marc Mundt · Mar 14, 2022 How about polling the global looking for updates? It would be lightweight to just check if the value of ^FSLOG has incremented since the last check: set lastFSEntry = ^FSLOG or use $order: set lastFSEntry = $order(^FSLOG(""),-1) As for timestamps, in my test environment all of the ^FSLOG entries seem to end with timestamps already: ^FSLOG(41)="DispatchRequest^HS.FHIRServer.Service^11062|Msg| [1] -> DO 0|03/14/2022 01:57:19.398158PM"

go to post Marc Mundt · Jan 11, 2022 Request.AdditionalInfo is defined as an array of AdditionalInfoItem, so the methods for working with that array are documented under ArrayOfObjects. For an array, GetAt expects a key rather than a numeric index. For example GetAt("ClientAddr") should work.

SELECT EnsLib_HL7.Message.RawContent INTO :FullMessage, head.ID As ID, {fn RIGHT(%EXTERNAL(head.TimeCreated),999 )} As TimeCreated, head.SessionId As Session, head.Status As Status, ... Also, I've gotta make a plug for keeping in mind the disclaimers on the use of RawContent:Note that this is a truncated version suitable for use in SQL results and visual inspection, but not a complete or definitive representation of the document.
go to post Marc Mundt · Dec 9, 2021 I'm not sure if you're looking at the ^ERRORS global directly or viewing it in the management portal under System Operation >> System Logs >> Application Error log. If you're doing the former I'd suggest switching to the latter as it's easier to see what's what. If you want to post a screenshot from Application Error log the community can chime in, but I'd suggest getting the WRC involved to take a look.
go to post Marc Mundt · Nov 16, 2021 You can create a custom REST web service, use Muhammed's approach to fetch the data, and then output the raw CSV as the response. One complication here is that %DisplayFormatted only outputs to files. You could consider outputting to the file, then read that file and output it in your response, but in a web service it would be best to output to the response directly. In that case, you might just iterate through the result set using %Next() and either use %Print(",") to output each row or build your own row by using %Get for each column to output and adding commas between columns.
