Master Data

Before myWMS LOS can be taken fully into operation, it must be provided with appropriate master data. This master data is the basis for the procedures. They may only be modified by users with the role ‘Admin ‘. For the data input and maintenance the customer is responsible and he adaptes it to his individual requirements

1. Setting up master data

To set up the master data please go one by one. Between the various master data there are dependencies that have to be observed and entered. First read in this document about what is required. Then, define master data in the given order.

2. Program Master Data

2.1. Roles

The permissions in myWMS LOS are granted by a role based concept.
In this concept, a role has designated permissions.
A user has one or more roles. He inherits the permissions of the roles.
The following table shows an overview over the predefined roles of myWMS LOS. 

name of role

assigned to



System Administrator




Perform stock changing operations


Store Operato

Goods in / Goods out / Transportation


Store Forema

Advanced permissions in operative business



Handle clearing events

Special dialog permissions Admin

Entity explorer
CRUD operations directly on the selectes entities Edit, Create and Delete in detail-area of the dialog.

2.2. Clients

The functionality of the client is implemented for the purpose of ‘One warehouse with one responsible operator and some large customers’.
The system client (operator) has all permissions. He is able to work unrestricted with the data of all clients.
A major customer (client) is only permitted to work with his ‘own’ data. The data of other clients/customers is not visible to him.
The private data of a client is for example material, storage locations, stocks and orders.
There is also non-client related master data. These are general master data of the warehouse. These data is available to all clients, but can only be maintained by the system client.
The client control can be used in different ways:

a) Only one (system) client.
This eliminates the functionality of client control. But the overhead is eliminated too.
b) More than one client, all users are assigned to the system client.
It is possible to distinguish between the material and stocks of the clients. The handling of all processes can be done by every user.
With the optional definition of client-assigned storage locations, it is  possible to distinguish the physical storage of the materials.
c) More than one client and client-assigned users.
Not only the materials and stocks are distinguished. The handling processes are distinguished too. The simple client is only permitted to handled ‘his own’ processes and data.
This option is useful, if i.e. a major customer should have a direct insight into the system. But he should not have access to the data of other customers.
Hybrids with option b) are possible.  

Detailed description of the fields:
Name of the client.
ID: ID of the client.
Number: Number of clients. This field is displayed in the dependent data sets.
System Client: This flag is set to true for the ‘owner’ of the warehouse.
Telephone, email, fax: address of the client. Just for info.

2.3. User

myWMS LOS is handling system access with an user account. In order to access the data of the system or launch any actions, an identification is necessary. Currently, the authentication with user name and password is provided. By assigning a user to a client access permissions (see client) are controlled.

Screenshot Dialog mywms-los Client Users

Detailed description of the fields:
First name
, last name, phone, email: address of the user. Just for info.
Locale: language code used in the presentation of the program interface.
Name: The login name. This value is entered to log into the system.
Password: The password of the user. It is shown encrypted  in MD5 in this view. When editing the password is entered in plain text and automatically encrypted when saved.

2.4. System Properties

With the system properties, certain features of myWMS LOS can be configured. System properties are client- and workstation related. That means that a property can be set separately for a client or for a workstation. E.g. the default value for the goods receipt location is stored in a system property. So at the terminal on ramp 1 this gate is shown, whilst on the terminal at ramp 2 the other gate is shown.

Screenshot Dialog mywms-los Client System properties

2.5. Jasper Reports

As a standard tool for creating reports myWMS LOS uses Jasper Reports. The forms or layouts required for the generation of a report are created in the database.

The reports are client-dependent. e.g. for each client his own layout can be deposited. For each layout must also exist an entry for the system client. This is used as default if no client specific layout is stored.

The reports can be read as XML files (Jasper Reports JRXML). During runtime these are compiled once and stored in compiled form in the database. When calling the individual reports no new compile is necessary.

Note! The report definition depends on the used version of Jasper Reports. As a compiler ‘Java’ must be given. Sub-reports, or other methods that cause an ambiguous layout are not supported.

The dialog shows the available reports.

3. Store Master Data

3.1. Zones

With zones special requirements of storage are modelled. The zone references both the storage location and the material. When searching for a location during storage process this assignment is taken into account. Only a location in the appropriate zone will be proposed. 

This classification can be used for:

  • ABC classification
  • Dangerous goods
  • Cooled products

The store is divided into A-B-and C-zone.
First define the zones. You can then assign these zones to location master data and item data on setup or provide the zones with the import files. 

Screenshot Dialog mywms-los Client Zones

3.2. Location Clusters

Location cluster help in the spatial organization of the storage.It combines storage places with the same (spatial) properties. In the work areas then will be directed only to the location cluster.

Screenshot Dialog mywms-los Client Location Clusters

3.3. Functional Areas

The predefined functional areas form a logical layout of the warehouse. Each storage location must be assigned to a functional area.

Screenshot Dialog mywms-los Client Function Areas

Detailed description of the fields:
A unique identifier.
Stock: Complete unit loads can be stored and rearranged.
Replenish: The material is available for replenishment.
Picking: The material is made ​​available for the picking.
Goods in: Use for goods in.
Goods out: Use for goods out.
Transfer: transfer locations

3.4. Working Areas + Positions

The working areas determine where myWMS LOS automatically searches for assignable orders. E.g. orders in a forklift control system.To each working area belongs a list of storage groups. Dispatchable orders must be based on storage areas with the respective groups.Since the working areas are based on the storage groups, all storage areas must be assigned to groups. Orders that refer to places without storage group can not be processed.

Screenshot Dialog mywms-los Client Working Areas

3.5. Unit Load Types

Each unit load is assigned to a unit load type. The unit load type describes the general characteristics of the unit load, such as dimensions or weight.

These types are used to e.g. control the occupancy of storage locations.

Please be cautious with the definition of various types. There are limitations, for example that only identical types may be stored on a storage location. Are there too many different types defined, the storage locations cannot be used optimally. 

Screenshot Dialog mywms-los Client Unit Load Types

Detailed description of the fields:
A unique key.
Height, width, depth: Dimensions. Just for info.
Weight: The weight of the unit load.

3.6. Storage Location Types

Each storage location is assigned to a storage location type. The storage location type describe the different physical storage locations.
By the type the strategies determine how the storage location is occupied.

Screenshot Dialog mywms-los Client Storage Location Types

Detailed description of the fields:
A unique key.
Height, width, depth: Dimensions. Just for info.
Lifting Capacity: The maximum allowable weight.

3.7. Capacities

Capacity constraints are rules that control the allocation of the storage locations. For this, the unit load type is set in conjunction with the location type.
In the dialog, you give rules, how much percentage one unit loads of a certain type allocates a storage location of a certain type.

If there are no constraints on a storage location, all unit loads are allowed to be put on this location. This is used to handle system locations or handover locations.

Screenshot Dialog mywms-los Client Capacities

Detailed description of the fields:
of storage locations: A unique key.
Type of unit load: the dimensions. Just for info.
Type: The method for storage location allocation

One unit load type. On the storage location only one type of unit loads is allowed
• Mixed unit load types. On the storage location various types of unit loads are allowed

Allocation: Percentage. Proportion of the storage location which is occupied by a unit load.

3.8. Racks

Through the masta data racks and aisles storage locations are grouped.

Screenshot Dialog mywms-los Client Racks

Detailed description of the fields:
: A unique identifier.
Aisle: The identifier of the aisles, where the rack is located

Description of functions:

Sorting storage locations: With this function, the picking sequence of the storage locations of the shelf are recalculated. The picking order bases on the sorting index of the storage location. This index is rewritten with this dialogue. Starting from an initial value the storage locations get a new sorting index depending on their X, Y and Z coordinates.

With this method different walks can be given for one aisle. E.g. on the one side and back the other, or both sides simultaneously.
Various courses can be syncronised by the start value.

Screenshot Dialog mywms-los Client Order or Locations

3.9. Storage Locations

In this dialog, all storage locations of the warehouse are defined.

Before starting with the definition of storage location, it is useful to think about the labels.

The manually or via forklift operated warehouse consists of shelves that are typically backside joined together. Each shelf is accessible from a lane that branches off from the center aisle. Each shelf is made of storage compartments in the horizontal and vertical directions. The area between two shelve uprights is known as the field. All storage locations have certain dimensions and are for the single depth intake of unit loads (eg Euro pallets) designed.

On the traverses per each storage location a label is placed, on which the storage location name is encoded as a bar code and in plain text and possibly a check digit.

The name of the storage location should be easy to recognize visually. It has to be entered or scanned to identify the location. If it is scanned per barcode, the code should be as compact as possible.

Another issue is the sorting of the picking orders. They are sorted by the location names! Should picking use simultaneously locations on the left and right, the naming must be different than if first all left and than all right locations are used.

A logically clear and easily recognizable subdivision is important in any case.

Example: A4-021-3

A4 = Rack or Aisle
02 = Field in Rack
1 = Location in field
3 = Level
Der storage location A4-021-3 is the fourth rack in hall A, there in the second field the first location in the third level.
