Thanks for your solution. Yes it worked for PR1 but for DG1 we are not getting object of type Varies. Say if I am getting a object of type ca.uhn.hl7v2.model.v23.datatype.NM then I am getting type cast exception like " ca.uhn.hl7v2.model.v23.datatype.NM cannot be cast to ca.uhn.hl7v2.model.Varies". Any help on this kind of cases?

The PR1/DG1 segment classes should append anonymous and untyped fields of type ca.uhn.hl7v2.model.Varies, containing GenericPrimitives or GenericComposites, which in return contain the values, and you can use the generic API (dg1.get(50), terser.get('DG1-50'), etc.) to access them. If you want to be more specific (access fields by name, validation etc.) you have the option to define custom segments and custom messages that exactly reflect your message semantics. See e.g. http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/examples/CustomModelClasses.html for an example. regards Christian rroy wrote: > > Hi, > > Is there a way that I can extend/augment the field numbers in PR1 and > DG1 segments based on my requirement?
