HU Monitor
Application component: Processing
App type: SAP GUI
Description:   You can use an evaluation report to issue a list of handling units. By entering selection criteria, you can limit the list of handling units and then display the list using the ABAP List Viewer (ALV) . In the list itself, you can process the selected handling units or make posting changes as required.  
Key features:   You can limit the search for handling units by using the following selection criteria:  HU general data Contents Assignment to objects User Freely-defined fields  If you enter a material or batch, for example, in the selection criteria for the contents of a handling unit, the system will display the highest-level handling unit with its individual items. You can then make posting changes within the ABAP list viewer. If you only want to display the higher-level handling unit for the selected contents, you must select the Search only in the next higher-level HU (quick search) option in the Contents section. However, if you choose this option, you cannot make any posting changes within the ABAP list viewer.  The following functions are possible in the list that appears: Displaying handling units Editing handling units Deleting handling units Making posting changes for the stock category for all materials in a handling unit (from blocked to unlimited-use, for example) Making posting changes for materials of a handling unit from one storage location to another Displaying a handling unit’s history Displaying change documents for a handling unit Making status changes (block/unblock a handling unit)  List display   The following options are available for displaying the selected handling units:  Handling units with cumulated material items In the dual-level ABAP List Viewer, the (highest-level) handling unit appears in the header line and the material items are cumulated according to material in the material lines. Handling unit hierarchy with totals and auxiliary packaging materials  In the header line for each HU, the system displays which material the HU contains and in what quantities (if the HU only contains one material). If the handling unit contains more than one material, the word MIX appears instead. Expand an HU in order to display the contents of it. Each lower-level HU and its contents is displayed separately. This list includes subtotals that group together similar HUs or HUs that are similar in some aspects. These subtotals are marked in a different color than the lines that represent the handling units. You can record in which sequence these subtotals are to be created by using Subtotals... in the ALV. For example, you could define the following sequence: Amount (1)/Material number (2)/Load carrier (3)/ Cumulated quantity of material to be packed (4). This setting results in the following:  As soon as a handling unit whose quantity of material to be packed (4) is different from that of the previous handling units appears in the HU list, the first subtotal is calculated (*). This first subtotal indicates the amount of grouped HUs up to this point. As soon as a handling unit whose load carrier (3) is different from that of the previous handling units appears in the HU list, the second subtotal is calculated (**). This second subtotal indicates the number of HUs that were grouped up to this point. As soon as a handling unit whose material (2) is different from that of the previous handling units appears in the HU list, the third subtotal is calculated (***). This third subtotal indicates the amount of grouped HUs up to this point. At the end of the list, the total amount (4) of HUs is taken as the fourth subtotal (****).  Note For example, if the material changes first (third subtotal), but the load carrier does not (second subtotal), the second subtotal is still calculated. Single-level list of handling units  The single-level ABAP List Viewer display is suitable for displaying handling units that contain only one material. The material and quantity are displayed for each handling unit. For handling units containing more than one material, the word MIX appears. You cannot make any posting changes in this display format.
