Purpose

This WS is designed to prequalify Service request: check the ability of create Service request within the Medical program

Specification

Preconditions

1. must be an active encounter

Logic

This method is used to pre-qualify service request in order to define whether the medical program could be applied in this particular case or not

Input parameters
