Graphical Warehouse Layout
Application component: Master Data
App type: SAP GUI
Description:  The graphical warehouse layout displays the interior and exterior of the warehouse as a two-dimensional graphic. You can use the graphical warehouse layout to check the Customizing of the warehouse. For example, if you are a warehouse supervisor or expert, you can check master data that you have defined in Customizing for Extended Warehouse Management (EWM). You can also get information about the stock situation, for example about empty storage bins and resources. The graphical warehouse layout displays the warehouse data per warehouse number. For example, if you are using warehouse number 1122 for a warehouse and warehouse number 1133 for a yard, the GWL shows you the warehouse data for the warehouse in the first case, and the warehouse data for the yard in the second case. 
Key features:   Displaying the Warehouse Layout You can check the Customizing for a warehouse number. For example, the graphical display enables you to quickly identify whether a shelf is incorrect due to you having entered incorrect data in Customizing. The default values are the warehouse number and storage type level you specified in Customizing. If you do not define a storage type level, the graphical warehouse layout displays all the objects that belong to a warehouse number. You can change the default values. For more information, see Customizing for EWM under Master Data  Define Warehouse Numbers or Master Data  Define Storage Type. If you only want to check Customizing for a particular part of the warehouse, such as for the goods receipt area, you can also specify the storage type in the default values. You can only refresh the display of the graphical warehouse layout for objects that change in the warehouse as part of your daily work, such as handling units or resources. However, if you display a warehouse, and then create new storage bins and refresh the display, EWM does not show the new storage bins. The graphical warehouse layout shows you master data for a warehouse number, such as storage bins or walls, in the form of a two-dimensional graphic. Here the length details in the graphic correspond to the unit of length that you defined as a base unit of measure in Customizing. For more information, see Customizing for EWM under Master Data  Define Warehouse Number Control. In addition, the display size relates to the largest coordinates that you have defined for a master record. This enables you to quickly identify for example whether a rack was defined incorrectly and is located outside the warehouse. You can choose the Zoom In and Zoom Out pushbuttons to change the graphical display, to display either the entire warehouse or individual objects in the warehouse. If the display size does not allow you to display the entire warehouse, you can choose the corresponding pushbutton to navigate upwards or to the right, for example. Here you use a percentage value to define the percentage of the current display size by which EWM is to change the graphical display in the respective direction. If you have generated storage bins using a template in Customizing for EWM under Master Data  Storage Bins  Define Storage Bin Structure, EWM groups the storage bins that are located on one side of the aisle into racks by default. Prerequisite for this is that you have defined the template in Customizing in such as way that the one side of the aisle contains stacks with even numbers, and the other side of the aisle contains stacks with odd numbers. The graphical warehouse layout can display these racks. Note If you choose Extended Warehouse Management  Master Data  Storage Bin on the launchpad and create storage bins individually, you must also fulfill the above prerequisite so that EWM combines storage bins into racks and displays these racks in the graphical warehouse layout. To switch to the front view of a rack, click the graphical display of the rack. This means that, even for multi-level racks, all storage bins are visable. If you choose Bin Level, EWM displays the individual storage bins instead of the rack. If you want to change the display for the graphical warehouse layout, you can use Business Add-In (BAdI) /SCWM/EX_GWLMC BAdI: Function on Mouse Click. For more information, see the relevant BAdI documentation in Customizing for EWM under Business Add-Ins (BAdIs) for Extended Warehouse Management  Monitoring.   Information and Functions for Existing Objects You can display detailed information for an object. The graphical warehouse layout displays a popup containing detailed information or actions for the object. If you want to display your own object-specific information or actions in the popup, you can use BAdI /SCWM/EX_GWLDISPLAY BAdI: Change Display of GWL. For more information, see the relevant BAdI documentation in Customizing for EWM under Business Add-Ins (BAdIs) for Extended Warehouse Management  Monitoring. You can call a context menu for the object and execute object-specific functions. If you want to define your own object-specific functions, you can use the BAdI /SCWM/EX_GWLCM BAdI: Extend Context Menu. For more information, see the relevant BAdI documentation in Customizing for EWM under Business Add-Ins (BAdIs) for Extended Warehouse Management  Monitoring. The following shows examples of objects containing object-specific functions:  Storage Bin You can use the context menu to navigate to the transaction for changing storage bins (transaction /SCWM/LS02), and change the coordinates of a storage bin, for example.  Handling Unit on Conveyor Belt You can use the context menu to display detailed data for a handling unit.  Workers You can send an e-mail to the worker.  You can display empty or blocked storage bins. If the storage bins are filled, EWM displays the information of the storage bins of the lowest level. If the storage bins are empty, EWM also displays the empty storage bins of other levels. In the standard system, No Selection is selected. If you want to display additional selection options, you can use BAdI /SCWM/EX_GWLMARKER BAdI: Define Additional Marker. For more information, see the relevant BAdI documentation in Customizing for EWM under Business Add-Ins (BAdIs) for Extended Warehouse Management  Monitoring.   Definition of New Objects You can define your own objects For more information, see Customizing for EWM under Monitoring  Graphical Warehouse Layout  Define GWL Object.
