DT or DTM Year only = Year - 1

[sgtcmofo]

Using ORU_R01 template and noticed that if just a year is passed into it, it is converted to the year -1.

Data to replicate:

OBX|52|DT|77999-3^Only Year^LN||2007||||||F

Hi @sgtcmofo ! Are you still getting this error? We are not able to reproduce this - are you able to provide more information for us to investigate?
