Invoice_Type_SupplierCredit

Invoice_Type_SupplierCredit = 4

Example​

procedure ScriptEvent(var Value: variant);
begin
  // Existing scripts may still use the compatibility alias.
  if Invoice_Type_SupplierCredit = Type_SupplierCredit then
    Value := Type_SupplierCredit_String; // 'SupplierCredit'
end;

Usage​

Invoice_Type_SupplierCredit provides deprecated invoice-type alias value 4 for compatibility with scripts that predate Type_SupplierCredit.

Additional Technical Info​

Invoice_Type_SupplierCredit is a deprecated compatibility alias for the supplier credit invoice type. Its fixed LongInt value is 4, identical to Type_SupplierCredit. Existing scripts can continue to read it, but new or revised scripts should use the Type_* identifier family.

The alias identifies an invoice type; it does not create, classify, validate or persist an invoice.

Implementation

Current native source places Invoice_Type_SupplierCredit in an explicitly deprecated block and assigns it value 4. The PascalScript importer still registers the alias as a LongInt for backwards compatibility. The preferred Type_SupplierCredit constant is independently registered with the same value.

A fresh VxData database seeds Invoice_Type row 4 with code SupplierCredit. Invoice_Hdr.TypeNum has a foreign key to that numeric domain. Current GetInvoiceTypeNum and GetInvoiceTypeCode implementations use the preferred Type_* constants and their String partners, not the deprecated Invoice_Type_* names.

Behaviour

Reading the alias produces exactly the same integer as Type_SupplierCredit. Once evaluated, the integer carries no information about which identifier spelling the script used. Deprecation is advisory in the current scripting surface: the name remains registered and does not itself emit a warning.

The Velox constant tag map exposes Type_SupplierCredit, not Invoice_Type_SupplierCredit. Use <!Type_SupplierCredit!> where a numeric configuration tag is required.

Edge cases and quirks

  • There is no Invoice_Type_SupplierCredit_String compatibility constant. Use Type_SupplierCredit_String for the canonical code.
  • Numeric invoice-type values are not type-safe in PascalScript and overlap values in other type/status families. Use the identifier belonging to Invoice_Hdr.TypeNum or another explicitly documented invoice-type field.
  • The generated index does not currently carry a deprecation flag for this page even though native source marks the alias deprecated. The source-backed deprecation guidance therefore appears in the Markdown body.
  • No removal version is declared in current source. Do not infer either permanent support or a specific removal date.

Side effects

Reading or comparing Invoice_Type_SupplierCredit has no I/O or state-changing side effect. Persisting 4 or running invoice processing is behaviour of the caller.

Errors

Reading the alias does not raise an error. Using the integer in the wrong numeric domain can select incorrect logic; persisting an invalid type outside the seeded Invoice_Type keys can fail the relevant database constraint.

Performance and concurrency

This is an immutable compiled value. Access is constant-time, allocates no persistent resource and carries no shared mutable state.

Remarks

The example is source-reviewed and non-destructive. Migrate the identifier spelling to Type_SupplierCredit when editing an existing script; the numeric result remains 4.
