When several HL7 event driver protocols share the same sending application, message type, event type, and version ID, the HL7 software will only retrieve the first protocol, even if it is not the correct protocol for the current message being processed.

INC2613742 - HL7 issue discovered with internal to internal messaging Problem: -------- The HL7 software currently reads from the "AHL1" or "AHL21" cross-reference in the PROTOCOL (#101) file to get the event driver protocol for the current message being processed. The cross-references are sorted by sending application, message type, event type, and version ID. If several protocols share the same sending application, message type, event type, and version ID, the software will only read the first entry in the cross-reference. The first entry is not necessarily the correct protocol for the current message, and this can lead to the incorrect protocol being returned. Resolution: ----------- The routine HLTPCK1A will be updated to no longer use the "AHL1" or "AHL21" cross-references, and instead use the message ID from the message header to retrieve the correct protocol for the current message.

It compares all of the components of this patch, such as routines, DDs, templates, etc. D. Select the Install Package(s) option and choose the patch to install. i. When prompted 'Want KIDS to INHIBIT LOGONs during the install? NO//', answer NO. ii. When prompted 'Want to DISABLE Scheduled Options, Menu Options, and Protocols? NO//', answer NO. Post-Installation Instructions: N/A Back-Out/Roll Back Plan: ------------------------ Prior to installing the updated KIDS package, the site/region should have saved a backup of the routines in a mail message using the Backup a Transport Global [XPD BACKUP] menu option. The message containing the backed up routines can be loaded with the "Xtract PackMan" function at the Message Action prompt. The PackMan function INSTALL/CHECK MESSAGE is then used to install the backed up routines onto the VistA system.
