Good question hope someone will attend it, actually I was also looking for something similar like PID.3 mapped with SDAX.FieldY 

Does it support with HS2020 version? I tried to import the xml but it giving error on the studio. Any steps to follow for installation

I think its not my lucky day, as i check message schema category and its says 2.5, may be i am running my rules . Also msg viewer shows blue font so message is correct but somehow method not able to parse HL7 values.

may be i am testing them from the rules editor thats why its not recognizing HL7 values ?
