Design Rationale

Functional Requirements

Logon to Logistics Mobility Solution

On starting the Logistics Mobility Solution on a mobile device, the user will logon using their single sign on network credentials and an agreed form of multi-factor authentication. The authentication method will be OAuth.

The user will be asked to set a PIN at the time of logon. This can later be used to re logon on a shared device, instead of having to repeat the full logon process.

After a successful sign on, the launchpad with the tiles for all the available apps will be shown. 

The user must have a Forgot Password option that will allow them to reset their password on the mobile device.

Switching User / Logout

At any time the user can choose to return to an initial screen that will list all users actively logged on to the mobile device. From this screen the user can choose to fully logout of the Logistics Mobility App, or to logon again using the PIN that was entered at the time of the initial logon.

CMMC 2.0 requirements must be followed. This includes the requirement that idle sessions must be logged out after an agreed period.

Logout

After choosing to logout of the Logistics Mobility Solution the user will be logged out of SAP and the mobile app will close.

Postings from Logistics Mobility Solution apps

A custom table will store the details of all the postings made from Logistics Mobility Solution Apps, including the app name, document processed, username, date, time and message back from SAP.

In the Mobile Admin app (ERP-712) the user has the option to see the information of their own postings. The desktop Handheld Manager app (ERP-713) will allow all postings from all users to be shown.

Shared logic used by all mobility apps

Barcode decoding logic

The primary barcode symbology for the solution will be GS1 Data Matrix, but other barcode symbologies like CODE 128, GS1 128, Data Matrix and QR Codes will also be supported.

All scans are to automatically include an enter key after the barcode content.

Scans of GS1 Data Matrix barcodes, CODE 128 or GS1 128 barcodes will populate all applicable fields, from a single scan, without the need for the user to manually select fields.

The solution must support scanning on the different mobile devices used by SyWay and also will support execution on smartphones.

Initial testing of scanning functionality will be done on smartphones.

Determine if HU is IM or EWM and calculate the cumulated content

All apps involving the scan of handling units will need to determine if the HU is an IM HU or an EWM HU. The logic described here will be used in all these apps.

• First check to see if the HU exists in ERP on VEKP-EXIDV
• If the HU exists on VEKP-EXIDV, calculate the cumulated content of the HU in IM.
  • If the storage location of the HU is an IM storage location, then the HU is an IM HU
  • If the storage location of the HU is an EWM storage location, then the HU is an EWM HU. Recalculate the cumulated content of the HU in EWM, since this may be different to the IM information.
• If the HU does not exist on VEKP-EXIDV, check to see if the HU exists in EWM on /SCWM/HUHDR-HUIDENT
• If the HU exists in EWM on /SCWM/HUHDR-HUIDENT then the HU is an EWM HU. Calculate the cumulated content of the HU in EWM.
• The cumulated content of each HU will store the material(s), batch(es), stock type(s) and quantity on the HU. 

Recommended UI Technology

The Logistics Mobility Solution (LMS) will be developed using Neptune DXP Open Edition.

LMS Postings

This table will store the details of all the postings made from Logistics Mobility Solution Apps, including the app name, document processed, username, date, time and message back from SAP.

The user has the option to see all their own postings for the day in this mobility admin app. The desktop admin app will allow all postings to be shown.

Front-End

The Logistics Mobility Solution will mainly be used on handheld scanners but can also be executed on the desktop.

Mobile Services

Not applicable

Authentication & Authorization

The logon to the Logistics Mobile Solution will use the OAuth authentication method in conjunction with an agreed form of multi factor authentication.

Users must authenticate against the Syensqo SSO infrastructure. The postings to S/4HANA must be made under the authenticated context of the person that made the posting from the device.

Logon to the Logistics Mobility Solution can be via WiFi, GSM or a wired LAN connection, depending on the available connection methods at the plant. 

The user must have a forgot password option, that allows them to process a password reset on the mobile device.

Accessibility

The logistics Mobility Solution will be primarily used on handheld scanners, with input from the scanner interface on the device.

Some apps will use the camera to allow photos to be taken and attached to SAP documents.

Volumetrics

This solution will be used at approximately 100 plants. The total users is estimated to be around 800.

Performance Consideration

Scanner input should be processed within 1 second, allowing multiple scans to be performed seamlessly with no need for the user to wait between scans.

Error Handling

Standard errors from SAP only.
