Advisory: HL7, X12, ASTM and EDIFACT Message Processing

InterSystems has corrected a defect that causes errors when updating segmented virtual documents such as HL7, X12, ASTM and EDIFACT. The error is triggered by a specific sequence of operations, namely:

1)   Clone an existing message OR create a message using a class method of the form ImportFrom…

2)   Use the method GetSegmentAt to fetch an individual segment of the message.

These steps cause the segment to be incorrectly marked immutable; it cannot be changed. Attempts to modify the segment fail with the message “<ENS>ErrGeneralSegment is immutable”

DTL (Data Transformation Language) usage is not at risk from this defect unless the GetSegmentAt method is explicitly called in a custom code block.

This Advisory applies to Ensemble and HealthShare on all platforms. This defect only exists in versions 2015.1 and 2015.1.1.

The correction for this defect is identified as JGM282. It will be included in all future releases of Ensemble and HealthShare. The correction is also available via Ad Hoc distribution from InterSystems Worldwide Response Center (WRC).
