E-WMS - Supported GS1-128 (EAN128) application identifiers

Introduction

This document describes what GS1-128 (former EAN128) 'Application Identifiers' are supported and recognized by E-WMS.

Description

A GS1-128 barcode can contain several types of information in one barcode, this creates the possibility to scan product code, batch code and quantity in just one scan.

Each part of the barcode is identified by an 'Application Identifier' (AI), in the sample above these are used:

02 Product identification EAN13 (14 digits)
15 batch end date (translates as December 1, 2011)
37 quantity (100)
$ group separator
10 batch code (09071)

AI's can be divided in two types:

AI's with a fixed length (like '02' and '15')
AI's with a variable length (like '37' and '10')

To mark the 'end' of an AI with variable length, a invisible 'separator' (GS1-128 'data terminator') is included in the barcode, unless the AI is the last part of the barcode.
In the barcode sample above, this separator is the '$' sign placed behind the quantity (0100).
This separator will be visible in a scanner barcode in E-WMS by the configured group separator.

The GS1-128 system knows many AI's (see: http://en.wikipedia.org/wiki/GS1-128), the most commonly used are supported by the WMS ASP hand terminal software:

AI	Supported in WMS ASP	Contents	Length type	Length	Format, remarks
00	yes	SSCC number *1	fixed	18	18 digits (17 digits + 1 control digit) *2
01	yes	EAN13/GTIN item identification	fixed	14	14 digits (13 digits + 1 control digit) *2
02	yes	EAN13/GTIN item identification	fixed	14	14 digits (13 digits + 1 control digit) *2
10	yes	batch number	variable		Maximum length of a S/B number in Exact Globe Next is 20
11	yes	production date	fixed	6	YYMMDD, applied as S/B start date for new S/B numbers
15	yes	best by date (quality), sell by date	fixed	6	YYMMDD, applied as S/B end date for new S/B numbers
17	yes	expiration date (safety)	fixed	6	YYMMDD, applied as S/B end date for new S/B numbers
21	yes	serial number	variable		Maximum length of a S/B number in Exact Globe Next is 20
23	No	lotnumber	variable	19	From PU422 onwards the 23n logic is followed. Example: A bar code contains $233123. “23” is the application identifier, “3” represents the number of digits of the lot number, and “123” is the lot number.
30	yes	quantity	variable	8	digits only, no decimals
37	yes	quantity	variable	19	Supported length in barcode is less than maximum length supported in Exact Globe Next (30)
90	yes	configurable in E-WMS	variable		Available from 414, maximum length is 30
250	yes	serial number	variable		Maximum length of a S/B number in Exact Globe Next is 20
310x	yes	quantity (net weight)	fixed	10 (4+6)	Using this AI you can supply decimal quantities. More details here.

*1: A SSCC number is recognized by E-WMS in Sales order fulfilment (to scan SKU numbers issued from, and to scan and register SSCC numbers used for shipping),
and in general WMS processes when using E-WMS SKU Management, to scan SKU numbers.
*2: Control digits (last digit in item GTIN or in SSCC number) are not validated as such when scanned in E-WMS.

Quantity and weight

When one scanned barcode contains multiple AI's for the same target field (quantity), then the numerical first AI will be applied.
So when a barcode contains both '30' and '310x' then 30 will be applied and '310x' will be ignored.

Recognized but not supported

The following EAN128 application identifiers are recognized but not supported in E-WMS, since recognition can be required to decode a complete EAN128 bar code.

AI	Supported	EAN128 content	Length
13	No	Packaging date	6
20	No	Product variant	2
22	No	HIBCC multiple data	29
240	No	Additional product ID	30
311 to 369	No	Product and container dimensions	6
400	No	Customer Purchase Order Number	29
410 to 412	No	Sender/receiver location codes	13
420 to 421	No	Sender/receiver ZIP codes	9, 12
8001	No	Roll Products - Width/Length/Core Diameter	14
8002	No	Electronic Serial Number (ESN) for Cellular Phone	20
8003	No	UPC/EAN Number and Serial Number of Returnable Asset	16
8004	No	UPC/EAN Serial Identification	30
8005	No	Price per Unit of Measure	6
8100 to 8102	No	Coupon Extended Code information	6, 10, 2
91 to 99	No	Free fields, internal data between trading partners	30
