GetOrderTypeForASNType

Function GetOrderTypeForASNType(const aASNTypeCode : string) : Variant;

Example

procedure ScriptEvent(var Value: variant);
begin
  Value := GetOrderTypeForASNType('CustomerASN'); // 'SalesOrder'
end;

Usage

GetOrderTypeForASNType maps a Velox ASN type code to its corresponding order type code.

Parameters and result

Item	Type	Description
aASNTypeCode	string, const	Canonical ASN type code. Matching is case-insensitive but otherwise exact.
Result	Variant	Order type code string for a recognized input, otherwise Null.

Behaviour and edge cases

• Customer versus supplier direction selects SalesOrder versus PurchaseOrder.
• Matching ignores ASCII letter case but does not trim. Whitespace, punctuation differences, empty text and unknown/custom type codes return Null.
• The function recognizes source-family codes only. Passing SalesOrder, PurchaseOrder or numeric text is not an identity conversion and returns Null.
• The result describes type/direction only; it does not copy, create, validate or change an order.
• The mapping is not extensible through customer configuration.
• Test VarIsNull before treating the result as a valid order type.

Additional Technical Info

GetOrderTypeForASNType converts a ASN type code into the canonical order type code that represents the same customer/supplier direction. It is a compiled business mapping; it does not inspect a document, order record, trading party or database configuration.

Complete transformation

Input ASN type code	Order type code	Order type number
CustomerASN	SalesOrder	1
SupplierASN	PurchaseOrder	2

Implementation

The function tests each supported input with installed Delphi SameText. It returns the literal Type_SalesOrder_String or Type_PurchaseOrder_String value. The final branch returns Null. There is no intermediate call to another public conversion function.

Side effects, errors and performance

The function is pure, performs no I/O and runs over a small fixed comparison chain. Ordinary unmatched string input returns Null.
