High- Level Specification

Functional Overview

This mobile app will allow barcodes to be decoded and will also provide an Data Capture option.

Barcode Decoding

Based on scanning a barcode, the application will show the raw content of the barcode, the barcode symbology and all the individual field content based on GS1 application identifiers.

Barcode decoding will be used for troubleshooting any barcodes that cannot be processed by the Logistics Mobility Solution.

Data Capture

The application will also provide a Data Capture option where multiple barcodes can be scanned to allow the barcode content to be stored on SAP in a custom table.

When the app is executed on a desktop, a reporting option will allow users to display the details of the scanned barcodes and transfer the results to a spreadsheet.

The Data Capture option will be useful to the business in a variety of scenarios including the capture of SSCC numbers for a specific selection of materials, for reporting or further processing on SAP on a desktop.

The application is to be named “Barcode Decoder”.

Scope and Objectives

Allows any barcode to be decoded and allows data capture of multiple barcodes.

Design Rationale

Functional Requirements

Initial Screen

The application will prompt for the user to scan a barcode.

A “Data Capture” button will allow the user to go to Data Capture mode where all scanned barcodes will be stored in a transaction list (Like other handheld apps) and finally saved and stored on SAP in a custom table.

A reporting option “Report Captured Data” will show only when the app is executed in desktop mode.

When a barcode is scanned, the barcode value will be decoded to derive all field content based on GS1 application identifiers.

See below for the GS1 application identifiers that need to be included in the decoding logic.

The application will display the raw content of the barcode, the symbology and all field values.

Data Capture

When the Data Capture option is selected, the screen will change to show that this mode is enabled. 

The user must enter a group name as this will later allow selection of the scanned information on the desktop. The group number can be any alphanumeric value and there is no validation on this field other than it being a mandatory field. 

The group name field will initially show the text “Enter a group name.”.

At the time of posting if no group name has been entered then show the error “Enter a group name.”.

Any barcode scanned will still be decoded with the existing decode logic but now scanned data will be stored in a scanned list like other handheld apps. In the scanned list the user will have the option to delete individual scans or all scans and to finally post the scanned data to SAP.

The scanned list will only show the SSCC number when present in the barcode or the entire barcode content when an SSCC is not present, but all decoded fields from the barcode scanned will be stored. 

Processing Data

At the time of saving the data captured, additional information will be determined based on the SAP database and then all scanned data and additional data will be added to a custom table in SAP.

Additional Data (IM and EWM)

Determine if the HU is an IM HU or an EWM HU and calculate the cumulated content. See ERP-1003.

Additional Data IM HUs

Additional Data EWM HUs

Scanned data.

Each field of scanned data in a GS1 barcode, as identified in the existing GS1 Decoder logic, will be stored in a dedicated field in the custom table.

Data Capture Report

When the GS1 Decoder app is executed in desktop mode, a button will be available for “Data Capture Report”. This option will allow the user to report on the previously captured data based on a selection by Userid, date and group name.

The report results will list all fields in the custom table and provide the option to download to Excel.

Recommended UI Technology

This app will be developed using Neptune DXP Open Edition. The app will appear on the Neptune launchpad.

Not applicable.

Volumetrics

The data capture option should support the scanning of hundreds of barcodes, as required.

Data captured will normally be used in the short term. Longer term it will be possible to purge records to reduce the table size. e.g. Records more than 10 years old.

Performance Consideration

Not applicable.

Error Handling

Errors to appear in a pop up window that needs to be acknowledged by the user.
