The GlideappCalculationHelper API is a scriptable object that
provides methods that add items to an existing request or request the recalculation of the price
of a request.

The methods for this API are used in global server-side scripts (script includes, business
rules, etc.). There is currently no support for scoped applications.

## GlideappCalculationHelper - addItemToExistingRequest(String requestID, String catalogID,
String quantity) {#ariaid-title2}

Adds a specific catalog item to an existing request. This API should be used only
before a request (REQ) is approved. After the REQ is approved, the RITM process is not
initiated.
