[mahalakshme]

Issue:

Currently rules having the below doesn't work in DEA

1. getSubjectsInLocation Example: Validation rule here
2. programEncounter.programEnrolment.individual.groups; Example: Visit schedule rule here - works
3. programEncounter.programEnrolment.findLatestObservationInEntireEnrolment('6cdf72fb-7885-4857-ad4c-9c26c3d65202'); Example: Visit schedule rule here: JNPCT - Adoloscent Followup Cancellation - not working but different simple solution can solve the problem without having to get all encounters
4. getEncounters() - not needed to support - another approach would ve worked in Visit schedule rule - IPH CTRITH - Child Anthropometry details - Visit schedule rule
