Type_CustomerCredit = 2

Example​

procedure ScriptEvent(var Value: variant);
begin
  Value := GetInvoiceTypeCode(Type_CustomerCredit); // 'CustomerCredit'
end;

Usage​

Type_CustomerCredit identifies Velox CustomerCredit invoice type 2 for scripts, tags and VxData transaction records.

Additional Technical Info​

Type_CustomerCredit is the canonical numeric identifier for the CustomerCredit member of the Velox invoice-type vocabulary. Its fixed LongInt value is 2, paired with Type_CustomerCredit_String.

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 fixed value 2. GetInvoiceTypeCode maps it to CustomerCredit; GetInvoiceTypeNum performs the reverse mapping. The numeric name is in the Velox tag map, so <!Type_CustomerCredit!> expands to 2.

For this exact token, GetOrderTypeNumForInvoiceType returns Type_SalesOrder and GetOrderTypeForInvoiceType returns SalesOrder. 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 CustomerCredit 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: customercredit is recognised and CustomerCredit is not. Unsupported text returns Null. Number-to-text conversion returns Null for Null or an unsupported number.

The 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

  • CustomerCredit identifies the Velox customer-direction credit type. It does not determine debit/credit sign, positive/negative totals, tax treatment or ledger posting.
  • The invoice-to-order bridge is directional: customer invoice and credit tokens both collapse to the same sales 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, comparing or tag-expanding Type_CustomerCredit 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.
