Type_SupplierPOD

Type_SupplierPOD = 2

Example​

procedure ScriptEvent(var Value: variant);
begin
  Value := GetPODTypeCode(Type_SupplierPOD); // 'SupplierPOD'
end;

Usage​

Type_SupplierPOD identifies Velox SupplierPOD proof-of-delivery type 2 for scripts, tags and VxData records.

Additional Technical Info​

Type_SupplierPOD is the canonical numeric identifier for the SupplierPOD member of the Velox POD-type vocabulary. Its fixed LongInt value is 2, paired with Type_SupplierPOD_String.

It selects an artifact-direction type. It does not create, load, validate, send, receive or change the state of a shipment, POD or tracking record.

Implementation

Velox declares and registers fixed value 2. GetPODTypeCode maps it to SupplierPOD; GetPODTypeNum performs the reverse mapping. The numeric name is in the Velox tag map, so <!Type_SupplierPOD!> expands to 2.

The POD converter is independent from the other two artifact-type converters even though all three families use customer value 1 and supplier value 2. Use GetPODTypeNum and GetPODTypeCode only for this family.

Database alignment

Fresh-build VxData seeds row 2 as SupplierPOD in Shipment_POD_Type, and nullable Shipment_POD.TypeNum references that table. Required Shipment_POD_Event_Type.TypeNum references the POD-type table and combines the type with Shipment_POD_Status for event behaviour.

The type-table code is exact SupplierPOD and the description is human-spaced. Code, number and display description are separate representations; persist the numeric key where TypeNum is expected.

Behaviour

Text-to-number conversion uses SameText, so case differences are accepted, but whitespace is not trimmed: supplierpod is recognised and SupplierPOD is not. Unsupported text returns Null. Number-to-text conversion returns Null for Null or an unsupported number.

The value has meaning only in its POD-type domain. The same integer in the other shipment artifact families, party roles, lifecycle statuses or transaction types is not a typed substitute.

Edge cases and quirks

  • POD means proof of delivery in this vocabulary, but selecting SupplierPOD does not prove delivery, validate a signature/image/PDF or establish evidential authenticity.
  • POD lifecycle StatusNum is a separate domain from this artifact TypeNum and from the general processing Status field.
  • Customer/supplier is a Velox artifact-direction label, not proof of sender, recipient, bill-from/bill-to roles, ownership or transport direction.
  • Numeric PascalScript constants do not retain a domain type after evaluation; validate the target field/table contract before assignment.
  • Text conversion is case-insensitive and non-trimming; String constants themselves remain exact compiled text.
  • A nullable record TypeNum may contain Null even though the seed vocabulary defines this value.
  • Selecting a type does not select a lifecycle status or trigger an event-routing row.

Side effects

Reading, comparing or tag-expanding Type_SupplierPOD has no database, file, network or shared-state side effect. Its converters are fixed in-memory mappings.

Errors

Reading the constant does not raise an error. Converter misses return Null; inputs outside the documented String/number contract can still encounter normal PascalScript Variant conversion behaviour. Persisting a value absent from the target type table can fail a database foreign key.

Performance and concurrency

This is immutable compiled metadata. Constant access and its two-branch converters are constant-time for practical purposes and do not carry mutable shipment state.

Remarks

Use the constant to make configuration intent explicit, then validate the surrounding dataset, direction, parties, lifecycle status and event configuration independently. The example is source-reviewed and non-destructive.
