hello @Ravikumar Puvvala, I do not believe that IRIS currently supports the following features that you require as per my knowledge and research. 

Here i will upload a link to the official documentation of the HL7 / FHIR ( changes made and how to handle them ) post. 

i hope this will be useful for you.

Hello there every one. 

I think I finally found the answer to my very own question. 

Thanks to @Kurro Lopez  for sharing that link with me. 

But then I believe that there is more to it. 

Thanks a lot by the way.
