SQM: Schedule query message
This page lists the structures and trigger events SQM defines, taken from the standard. The written commentary that theADT page carries has not been written for SQM.
Recognising SQM messages
SQM announces itself in MSH-9 like this:
SQM^S25^SQM_S25- MSH-9.1
SQMmessage code: what kind of message this is - MSH-9.2
S25trigger event: what happened in the real world: schedule query message and response - MSH-9.3
SQM_S25message structure: which segments to expect, and in what order
How to use these specifications explains MSH-9 in full, with a worked example.
Message structures
SQM takes 1 structure.
SQM_S25: Schedule Query Message and Response
Sent when one thing happens: S25: Schedule Query Message and Response.
You must always send: MSH, QRD. Everything else is optional, or required only inside a group you chose to send.
| Segment | Name | OPT | Cardinality |
|---|---|---|---|
| MSH | R | 1..1 | |
| QRD | R | 1..1 | |
| QRF | O | 0..1 | |
| REQUEST | a group of 4 segments, repeated together | O | 0..1 |
| ARQin REQUEST | R | 1..1 | |
| APRin REQUEST | O | 0..1 | |
| PIDin REQUEST | O | 0..1 | |
| RESOURCESin REQUEST | a group of 5 segments, repeated together | R | 1..* |
| RGSin RESOURCES | R | 1..1 | |
| SERVICEin RESOURCES | a group of 2 segments, repeated together | O | 0..* |
| AISin SERVICE | R | 1..1 | |
| APRin SERVICE | O | 0..1 | |
| GENERAL_RESOURCEin RESOURCES | a group of 2 segments, repeated together | O | 0..* |
| AIGin GENERAL_RESOURCE | R | 1..1 | |
| APRin GENERAL_RESOURCE | O | 0..1 | |
| PERSONNEL_RESOURCEin RESOURCES | a group of 2 segments, repeated together | O | 0..* |
| AIPin PERSONNEL_RESOURCE | R | 1..1 | |
| APRin PERSONNEL_RESOURCE | O | 0..1 | |

| AILin LOCATION_RESOURCE | R | 1..1 | |
| APRin LOCATION_RESOURCE | O | 0..1 | |
| DSC | O | 0..1 |
R inside a group means required of that group. Send the group and you must include that segment; leave the group out and it never appears. This structure has 6 such groups: REQUEST, RESOURCES, SERVICE, GENERAL_RESOURCE, PERSONNEL_RESOURCE, LOCATION_RESOURCE.
Trigger events
The trigger event is the real-world thing that made the message get sent. SQM defines 1.
