| GENERATE |
The
GENERATE^HLMA(HLEID,HLARYTYP,HLFORMAT,HLRSLT,HLMTIEN,HLP) entry point to used
to generate a HL7 message. It returns a unique message ID if a message is
successfully generated.
|
| VARIABLES |
TYPE |
VARIABLES DESCRIPTION |
HLEID |
Input |
The name or IEN of the event driver protocol in the
Protocol File (#101).
|
HLARYTYP |
Input |
Array type. One of the following codes:
LM = local array containing a single message
LB = local array containing a batch of messages
GM = global array containing a single message
GB = global array containing a batch of messages
|
HLFORMAT |
Input |
Format of array, 1 for pre-formatted in HL7 format,
otherwise 0
|
HLRESLT |
Both |
The variable that will be returned to the calling
application with either a error message or a unique message ID.
|
HLMTIEN |
Input |
Optional IEN of entry in Message Text file where the
message being generated is to be stored. This parameter is only passed for a
batch type message.
|
HLP |
Input |
The HLP parameter is passed-by-reference. The HLP
subscripts that are processed by GENERATE^HLMA are identical to the
DIRECT^HLMA HLP subscripts. These subscripts are listed below.
o HLP("PRIORITY") = I for immediate or D for deferred
o HLP("SECURITY") = A 1 to 40 character string
o HLP("CONTPTR") = Continuation pointer, a 1 to 180 character string
o HLP("NAMESPACE") = Free-text value, 4 character limit, stored that is
to be stored in the NAMESPACE field (#16) in the
HL Message Text file (#772.)
o HLP("SUBSCRIBER") = Free-text, multi-piece value, used to control the
routing-related fields in the MSH segment. See
patch HL*1.6*93 documentation for full details.

DIRECT |
The
DIRECT^HLMA(HLEID,HLARYTYP,HLFORMAT,HLRSLT,HLMTIEN,HLP) entry point is used to
generate a HL7 message. It returns a unique message ID if a message was
successfully generated. Unlike the GENERATE^HLMA API, the DIRECT^HLMA API
opens the connection directly for message delivery. (GENERATE^HLMA delivers
messages via queued background job.) Applications that use the DIRECT API must
provide the guaranteed delivery if needed.
Call INIT^HLFNC2 before making this call, to set up HL7 environment variables
needed to build your message and needed by DIRECT^HLMA.
The DIRECT^HLMA call has the same input parameters as GENERATE^HLMA. Like
GENERATE^HLMA, it expects segments for the message to be already loaded in the
HLA("HLS") local array or the^TMP("HLS") global array. For more information on
the expected format of HLA("HLS") or^TMP("HLS"), please see the GENERATE^HLMA
call.
To select the subscriber to transmit to, this call first checks the contents
of the HLL("LINKS")array; it will use first record it finds. If that array is
empty, it uses the first subscriber protocol it finds in the Subscribers
multiple of the event driver protocol.
Upon return, DIRECT^HLMA does not invoke the event driver protocol's
GENERATE/PROCESS ACK ROUTINE to processes the acknowledgment. When control is
returned to the calling routine, the environment is left in the same condition
as if you were in the "processing routine environment" when receiving an
acknowledgment; the variables HLNEXT,HLNODE, and HLQUIT are defined so that
you can process the response. Note that DIRECT^HLMA supports:
o All acknowledgment modes (including deferred acknowledgments
o Batch message transmission The timeout for the synchronous
transmission is determined by the settings of the TCP used.
Example:
D DIRECT^HLMA("EVENT DRIVER PROTOCOL","GB",1,.MYRESULT)
I +$P(MYRESULT,U,2) D ERR Q ; message was not transmitted
I HLMTIEN D PROCESS ; response was returned from target system

The variable that will be returned to the calling
application with either a error message or a unique message ID.
If the call is successful (message sent), the Result parameter is returned
with piece 1 equal to the message ID of the message created. If the call
failed (message was not sent), the Result parameter is returned with the
following three pieces of data:
message ID(0 if none assigned)^error code^error description
If the call failed, +$P(RESULT,U,2) returns True.

Optional IEN of entry in Message Text file where the
