Variable as repeating field index in property path
Ensemble 2017.2.
I am writing a DTL code action based on the solution described in the posting "How to avoid truncation in HL7 messages with very large fields (32K+)". Because the source value is in a repeating segment, and the specific repetition in which the value is located can vary, I would like to use a variable (specifically the k1 key) to specify the repetition to get. I have been unable to get it to work.
OBXgrp is the location in the path at which the repetition occurs. Hard-coding an index, as in the example below, works.
do source.GetFieldStreamRaw(.stream, "PIDgrpgrp(1).ORCgrp(1).OBXgrp(3).OBX:5.1")
However, if I use k1 instead, as in the example below, it fails to retrieve the data.
do source.GetFieldStreamRaw(.stream, "PIDgrpgrp(1).ORCgrp(1).OBXgrp(k1).OBX:5.1")
How can a variable be used as a repeating field index in a property path?
Hi Larry,
In a code rule, you'll need to concatenate the path string with the k1 variable, as such:
do source.GetFieldStreamRaw(.stream, "PIDgrpgrp(1).ORCgrp(1).OBXgrp("_k1_").OBX:5.1")
