Type_SupplierInvoice_String

Type_SupplierInvoice_String = 'SupplierInvoice'

Example

procedure ScriptEvent(var Value: variant);
begin
  Value := GetInvoiceTypeNum(Type_SupplierInvoice_String); // 3
end;

Usage

Type_SupplierInvoice_String provides the exact SupplierInvoice text paired with Type_SupplierInvoice for the Velox invoice-type domain.

Value

Property	Value
Script type	String
Text value	'SupplierInvoice'
Paired number	Type_SupplierInvoice = 3
Deprecated numeric alias	Invoice_Type_SupplierInvoice = 3
Database domain	Invoice_Type.Num; Invoice_Hdr.TypeNum
Tag-map entry	No

Additional Technical Info

Type_SupplierInvoice_String is the canonical text for the SupplierInvoice member of the Velox invoice-type vocabulary. Its fixed String value is 'SupplierInvoice', paired with Type_SupplierInvoice.

It selects a domain value; it does not create, load, validate, send, receive, post or change the status of a transaction.

Implementation

Velox declares and registers exact text SupplierInvoice. GetInvoiceTypeNum compares it with Delphi SameText and returns 3; GetInvoiceTypeCode performs the reverse mapping. The String identifier is not in the Velox tag map.

For this exact token, GetOrderTypeNumForInvoiceType returns Type_PurchaseOrder and GetOrderTypeForInvoiceType returns PurchaseOrder. Invoice and credit tokens in the same direction intentionally converge on the same order type; the bridge does not preserve whether the source document was an invoice or a credit.

Database alignment

Fresh-build VxData seeds this exact row in Invoice_Type. Invoice_Hdr.TypeNum is a nullable foreign key to that table; Invoice_Event_Type.TypeNum is a required foreign key used with invoice status to select event behaviour.

The seed-table code is SupplierInvoice and its display description is human-spaced. The code, number and description are separate representations; persist the numeric key in TypeNum and use the exact code only where a code contract calls for it.

Behaviour

Text-to-number conversion is case-insensitive because it uses SameText, but it does not trim: supplierinvoice is recognised and SupplierInvoice is not. Unsupported text returns Null. Number-to-text conversion returns Null for Null or an unsupported number.

The paired numeric value has meaning only inside its invoice-type domain. Identical integers in party, source, status, shipment or other vocabularies are not interchangeable.

Edge cases and quirks

• SupplierInvoice identifies the Velox supplier-direction invoice type. It does not determine debit/credit sign, positive/negative totals, tax treatment or ledger posting.
• The invoice-to-order bridge is directional: supplier invoice and credit tokens both collapse to the same purchase order type.
• Numeric PascalScript constants do not retain a domain type after evaluation; validate the target field/table contract before assignment.
• The preferred name is numerically indistinguishable from its deprecated alias after evaluation.
• A nullable header TypeNum may contain Null even though the seed vocabulary defines this value.
• The constant does not enforce event configuration, party relationships, lifecycle transitions or business-document validity.

Side effects

Reading or comparing Type_SupplierInvoice_String has no database, file, network or shared-state side effect. Converter and bridge helpers, where present, 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, fixed converters and fixed bridge lookups are constant-time for practical purposes and do not carry mutable transaction state.

Remarks

Customer/supplier and sales/purchase naming expresses Velox's transaction vocabulary, not a universal accounting or EDI interpretation. Confirm the mapping contract, parties, signs and downstream process independently. The example is source-reviewed and non-destructive.
