Usage Note: This business identifier is assigned by the sending application and is used to group tasks together that need to be processed and managed together. There are some business scenarios where a given task will be managed individually (eg cancel request). If a particular task is not part of a logical group, it will have its own requisition identifier (i.e. it will be handled as a group of 1). In other scenarios, the same requisition identifier is assigned to multiple tasks as they are considered to be part of a group. Example: medications that would be part of the same written paper Prescription or Renewal request will share the same Requisition Identifier.

Usage Note: Tasks corresponding to different requisition identifiers may be present in the same Bundle. The recipient must take this into account when grouping content for display/actioning by requisition identifier.

Suggested Structure: Assigned by the EMR; scoped by the application instance; this is an OID. An OID may be structured as Vendor.ApplicationInstance.RX#Branch Ext = Requisition Id.

Conformance Rule: All task resources sharing a common requisition number must be transmitted in the same message bundle.

Conformance Rule: All medication orders sharing the same requisition identifier in a renewal request must be viewed, managed and responded to together.

Conformance Rule: Different task types can share a requisition identifier when a task was performed in the shared context of other tasks with the same requisition id. For example, medication 1 was discontinued in the same context that medication 2 was prescribed. Receiving systems SHOULD display/manage tasks that are part of the same requisition together when this is feasible.

Conformance Rule: In the context of a 401 - Execute deferred (prescription) tasks from an EMR, this will map to the 'PrescribeIT™ RX ID' on the printed Patient Copy.

Usage Note: Requisition ID would be used by PMS to establish which medications belong to the same prescription.
