HI Vamsi Reddy,
if you want to add CHANGED_BY , CHANGED_AT_RANGE into SRQM_INCIDENT_S/IncidentSR first
enhance the component and then enhance the view. identify the base_entity name of the search context node because this base_entity having search structure. then you have to append the fields to that structure.
that fields will available into your context node. move those fields from available to display into config mode.
in your case this is the procedure.
identify the base_entity btqsrvreq is base entity here.
go to dynamic query object identify the btqsrvreq under that objects then there is a structure exists.
click on that structure append those structure and then add your fields into that structure.
that fields will available into your search context node.
if you have any queries let me know.
Thanks & Regards,
Srinivas.
