definePrefix

Implementations

Google Sheets: Google Sheets: aidctGS1DefinePrefix(prefix, prefixType, tweakFactor)

Define a prefix for use in GS1 identifier creation functions.

Parameters

Name	Type	Description
prefix	String	Prefix.
prefixType	Number	Prefix type. Valid values are 0 (GS1 Company Prefix), 1 (U.P.C. Company Prefix), and 2 (GS1 Prefix).
tweakFactor	Number	Tweak factor, used to support the creation of sparse identifiers. The default tweak factor is based on the GS1 Company Prefix, and is usually sufficient for obfuscation. This allows more control over the encryption when higher security is required.
