Tracking_Cancelled

Tracking_Cancelled = 3

Example

procedure ScriptEvent(var Value: variant);
begin
Value := GetTrackingStatusCode(Tracking_Cancelled); // 'Cancelled'
end;

Usage

Tracking_Cancelled identifies the Cancelled shipment-tracking state as Shipment_Tracking_Status.Num value 3 for Velox scripts and mappings.

Additional Technical Info

Tracking_Cancelled is the script-visible LongInt identifier for the Cancelled shipment-tracking state. Its fixed value is 3, paired with Tracking_Cancelled_String.

It identifies a shipment tracking record and its event history. It does not load a row, validate a transition, persist a value or trigger delivery processing.

Implementation

Velox declares and registers the fixed LongInt value 3. GetTrackingStatusCode maps it to Cancelled; GetTrackingStatusNum performs the reverse mapping. The numeric name is registered in the Velox tag map, so <!Tracking_Cancelled!> expands to 3.

Fresh-build SQL seeds only row 1=Delivered in Shipment_Tracking_Status, although product source exposes Updated=2 and Cancelled=3. Tracking and tracking-event StatusNum fields reference the tracking status table. This page's value 3 is therefore recognised by product code but is not seeded by that fresh-build script.

Behaviour

Use the value only in the Tracking status domain. The fixed converters do not query VxData. Reading, comparing or expanding the constant does not assign a StatusNum field, change a lifecycle state or perform the action suggested by its name.

Tracking lifecycle StatusNum is separate from the general issue/presentation Status column on tracking and event rows.

Edge cases and quirks

  • Tracking and POD use the same three numbers and text, but have separate constants, converters and database tables.
  • PascalScript integers and strings retain no lifecycle-domain type information after evaluation; using a value with the wrong converter or field can silently express another meaning.
  • The text-to-number converter is case-insensitive but non-trimming. An empty string, surrounding whitespace or unsupported text returns Null.
  • The number-to-text converter returns Null for a Null or unsupported number rather than selecting a default.
  • The tag expansion produces the number 3, not the text Cancelled.
  • Before persisting Tracking_Updated or Tracking_Cancelled, verify that the target deployment has corresponding status rows. Also note that the current Shipment_Tracking_Event_Type definition points its type/status foreign keys at the POD tables, not the tracking tables; these constants do not repair that schema mismatch.

Side effects

Reading Tracking_Cancelled, comparing it, expanding its tag or using the fixed converter has no I/O or state-changing side effect. Database writes, event creation and workflow transitions come from the caller.

Errors

Reading the constant does not raise an error. Converter misses return Null. A database write can still fail validation or a foreign-key constraint, particularly where the deployed Shipment_Tracking_Status rows do not include the script-visible value.

Performance and concurrency

This is an immutable compiled value. Access and the short fixed-case conversions are constant-time for practical purposes and carry no shared mutable lifecycle state.

Remarks

The example is source-reviewed and non-destructive. It performs only fixed in-process conversion; it does not test or change a live shipment.
