High- Level Specification

Functional Overview

This mobile app will allow stock overview information to be displayed. This can be all stock for a storage location or limited to stock for a specific material, batch or storage bin etc. Drill down options will allow the user to see the information by stock type, batch, handling unit or storage bin level.

Scope and Objectives

This app will support stock overview reporting in IM and EWM.

Process Flow Diagram

Assumptions

Dependencies

Security, Integrity and Controls

The user must have material document display access for the selected plant. Check object M_MSEG_WMB for Activity 03 and the selected plant. If no access, show the message "No authorization for plant <9999>".

Configuration Requirements

None

Language Requirements

This app will be available in all SyWay languages.

Special Requirements

Design Rationale

Functional Requirements

Initial Screen

The first screen will prompt to enter Material, Batch and Storage Location. The values for these fields can be scanned or typed.

If the plant is using EWM there will be additional fields to enter Storage Type, Storage Section and Storage Bin. For EWM there will also be a checkbox to allow the user to report empty bins.

For scanning, the field input needs to support the 2D GS1 Data Matrix barcode format or other agreed formats. Material numbers will use application ID 240. Batch will use application ID 10. Barcodes for storage bin will have no application ID.

Any combination of values can be entered with the following exceptions:

• Batch can only be entered in conjunction with a material number.
• Storage Location can only be left blank if a material or material and batch are entered.
• Storage Section can only be entered if a Storage Type has been entered.
• The empty storage bins option can only be used with all selection fields blank, or only storage type and or storage section populated.

The plant and EWM warehouse for the user have already been established at the time of logon to the handheld solution. 

Initial Screen Validation                                                                      

<Example Initial screen>

Stock Overview screen

The Stock Overview screen will display a list of material stock based on the selection. The quantity displayed will be the total quantity of the material in stock per storage location across all stock types.  This is the same information reported in SAP transaction MB52, selecting by plant, batch and storage location and no zero stock lines.

<Example Stock Type screen>

The user will have the ability to filter the list based on the material or description to allow searching for a specific material.

Selecting a row in the table will take the user to the Stock Type screen. 

Stock Type screen

The material details screen shows the quantity of the material by stock type, based on the selection. This is the same selection as the MMBE transaction, selecting by material, plant, storage location, also select special stocks and special stock numbers e.g. Vendor consignment stock: K, Vendor: 29899, no zero stock lines and display level for plant and storage location.

If the location is handling unit managed (T001L-XHUPF = X) and the material exists in handling units, then a “Handling Units” button is displayed allowing the same material stock information to be displayed per handling units. This is the same selection as transaction HUMO selecting by material / plant / storage location. If the location is not handling unit managed, then this button will not be displayed.

If the material is batch managed (MARC-XCHPF), and the initial report selection was not by batch, a button “Batches” will allow the same material stock information to be displayed per batch. This is the same as the previous selection on MMBE but with the batch level selection switched on.

<Example Stock Type screen>

Batch Screen

The user will be presented with a list of all batches in stock for the material, based on the selection. If the storage location is handling unit managed, then a button “>” will also be available on the batch record, to allow branching to the Handling Unit screen for the selected batch.

The fields to be displayed for the handling unit are:

• Batch number
• Stock Type
• Quantity
• Expiry Date

<Example Batch screen>

Handling Unit Screen

The user will be presented with a list of all handling units in stock for the material, based on the selection. Only the highest-level handling units are displayed so if a box is on a pallet only the handling unit for the pallet is displayed.

The fields to be displayed for the handling unit are:

• Handling Unit
• Packaging Material. E.g. Pallet
• HU System status
• Material
• Batch number
• Stock Type
• Quantity
• UOM
• Expiry Date

<Example Handling Units screen> 

A button “>” per HU, will allow branching to the Display HU transaction, covered in FS ERP-788.

EWM Stock Screen

The user will be presented with a list of all stock for the material in the EWM warehouse, considering earlier selections by material, storage location, batch, storage type, storage section and storage bin.

For HU managed materials, only the highest-level handling units are displayed so if a box is on a pallet only the handling unit for the pallet is displayed.

The fields to be displayed for the handling unit are:

• Storage Type
• Storage Section
• Storage Bin
• Handling Unit
• Material
• Batch
• EWM stock type.
• Quantity
• UOM
• Expiry Date

When the empty bins option is used, this screen will also be displayed but only the empty storage bin information will be displayed.
