Parameters

parameter AllowNonMSA = 0;
Don't report an error for reply messages containing no MSA:1 field (Deprecated - use Setting ReplyCodeActions instead of subclassing)
parameter IndexACKs = 0;
[Deprecated] The SaveReplies property/setting should be used instead. Index ACKs if IndexReplies is also true and SearchTable class is given
parameter IndexReplies = 1;
[Deprecated] The SaveReplies property/setting should be used instead. If SearchTableClass is given, use it to index any replies (including ACKs unless IndexACKs=0 or OK and SaveOKACKs=0)
parameter SETTINGS = ReplyCodeActions,NoFailWhileDisconnected,SaveReplies;
Inherited description: List of properties can be set as settings in the configuration file format is a comma separated list of property names
parameter SaveOKACKs = 0;
[Deprecated] The SaveReplies property/setting should be used instead. Save OK ACKs
parameter SetReplyDocType = 1;
Set the DocType and MessageTypeCategory properties of the reply message if possible
parameter WarnACKControlId = 1;
Log a Warning if the reply MSA:2 ControlId does not match the original message's control ID (Deprecated - use Setting ReplyCodeActions instead of subclassing)

Properties

property %Parser as EnsLib.HL7.Parser;
Property methods: %ParserGet(), %ParserGetSwizzled(), %ParserIsValid(), %ParserNewObject(), %ParserSet()
property %replyActionMap [ MultiDimensional ];
parsed array property of ReplyCodeActions setting

property ReplyCodeActions as %String (MAXLEN = 1000);

A comma-separated list of codes specifying what action this Operation will take on receipt of various types of ACK response messages and other reply status conditions. The format of the list is:
<code>=<action>,<code>=<action>,...
Types of reply status condition are identified by a specification code: A <code> value starting with a colon - e.g. :<char><char> represents a literal value found in field MSA:1 of the response message. Also, the following special code values may be used:

  • :?A - matches AA or CA values (Accept)
  • :?E - matches AE or CE values (Error)
  • :?R - matches AR or CR values (Reject)
  • :_ - matches replies with an empty MSA:1 field
  • :* - matches any MSA:1 value not matched otherwise (default=F)
  • :~ - matches replies that do not contain an MSA segment
  • :I? - matches where the reply MSA:2 ControlId does not match the ControlId of the original message
  • :T? - matches where the reply MSH:9 Type name does not match the schema's declared reply type for the original message

The default behavior is ':?R=RF,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C'
This means for NACKs received with error code AR or CR retry, while codes AE or CE suspend the current outbound message and move on to the next.

Also, the following standard status conditions may be used:

  • E - Error status returned from message handler
  • E#<statuscode> - Error status returned from message handler has status code equal to <statuscode>
  • E*<text> - Error status returned from message handler contains text string <text>
  • X - there is no reply message at all

The following values for <actions> may be used alone or in combinations:

  • C - Treat the message as Completed OK.
  • W - Log a warning. If no other non-warning <actions> are triggered, the message will be treated as Completed OK.
  • R - Retry the message according to the configured RetryInterval and FailureTimeout; finally Fail unless a different action is also specified. Note this setting is separate from the Retry property.
  • S - Suspend the message, log an error, and move on to try the next message.
  • D - Disable the Operation, log an error and restore the message to the front of the Operation's queue.
  • F - Fail with an error and move on to try the next message from the Operation's queue subject to the Retry property value set in the code. If the Retry property is set in the code then moving on to try the next message will be subject to the configured RetryInterval and FailureTimeout. The HL7 TCP outbound adapter sets the operation's Retry property to true when there are network connection errors.
An example of a valid ReplyCodeActions specification is 'E#6301=R,E#<Ens>ErrGeneral=RD,E=F'. This specification will result in a retry when error code 6301 is encountered. When error code <Ens>ErrGeneral is encountered, the Operation first retries to send the message until FailureTimeout and then, if the error continues, it disables the Operation instead of failing. Any other errors will cause the Operation to fail processing of the current message and return the error status to the caller, without retrying first unless the property Retry has been set to true by the operation code.

All codes where <actions> consists of only 'W' (for 'log a Warning') will be evaluated, and a warning will be generated for each matching <code>. Other <code> values will be evaluated in left-to-right order, executing the first matching <code> that has a non-warning <actions> value. As noted in the details for the 'W' flag, an error that only triggers 'W' <actions> will be treated as Completed OK.

Property methods: ReplyCodeActionsDisplayToLogical(), ReplyCodeActionsGet(), ReplyCodeActionsIsValid(), ReplyCodeActionsLogicalToDisplay(), ReplyCodeActionsLogicalToOdbc(), ReplyCodeActionsNormalize(), ReplyCodeActionsSet()
property SaveReplies as %String (VALUELIST = ",None,NotOKs,All,IndexNotOKs,IndexAll") [ InitialExpression = $select(..#IndexReplies: "Index"_$select(..#IndexACKs: "All", 1: "NotOKs"), ..#SaveOKACKs: "All", 1: "NotOKs") ];
Save a copy of reply messages sent back to the remote system. Also optionally index them using the configured SearchTableClass, if any.
The options for this setting are as follows:
  • None : Don't save or index any reply messages.
  • NotOKs : Save replies that are not a simple OK ACK message: e.g. error NACKS and query responses.
  • All : Save a copy of all reply messages sent back to the remote system.
  • IndexNotOKs : Save replies that are not a simple OK ACK message and index them using the configured SearchTable. This is the default behaviour, unless IndexReplies, SaveOKACKs or IndexACKs has been overridden in this class.
  • IndexAll : Save a copy of all reply messages and index them using the configured SearchTable.
Property methods: SaveRepliesDisplayToLogical(), SaveRepliesGet(), SaveRepliesIsValid(), SaveRepliesLogicalToDisplay(), SaveRepliesLogicalToOdbc(), SaveRepliesNormalize(), SaveRepliesSet()
