Basic Customizing for Handling Unit

1. a. IMG → Logistics - General → Handling Unit Management → Basics → Materials Management → Inventory Management → HU Requirement for Storage Locations and Default Values for Deliveries

HU Requirement for Storage Locations and Default Values for Deliveries

In this step, for each storage location, you maintain the handling unit requirement and the default values for creating a delivery.

You can override the default settings at plant level with more specific default settings at storage location level.

When you set the HU requirement indicator for a storage location, you can only make stock postings if you specify the handling unit. If you do not specify the handling unit, the system does not create a material document when you make the posting but creates a delivery document.

Since the stock in a storage location that is subject to a handling unit requirement is packed in principle, you must maintain a partner storage location for transactions such as unpacking. Use a storage location in the same plant as the partner storage location that has the same or no warehouse number.

Requirements

You are only allowed to change the indicator HU requirement for storage locations that do not contain any stock and that are not assigned to a decentralized warehouse management system.

Activities

Maintain data as required.

Further Notes

Storage locations that are assigned to a decentralized warehouse management system can be flagged as having an HU requirement in the decentralized Warehouse Management System.

b. Select the table entry for plant 1000 and go to the storage location level in the dialog structure.

c. Choose the entry for your storage location HU## and overwrite the partner storage location 0001 with the key for your storage location (01##).

d. Assign sales organization 1000, distribution channel 10, shipping point 1000, division 00, vendor 10000, and customer 10000 to your storage location HU##. Save your changes

2. Display the number range for internal system identification of the handling units. a) Choose SAP Reference IMG → Logistics - General → Handling Unit Management → Basics → Technical Basics → Define Number Ranges for Handling Units.

Define Number Ranges for Handling Units

When creating a handling unit, the system assigns a clear number internally. This number is from the number range interval, which you can maintain in this menu option.

Standard settings

An internal assignment is carried out in the standard delivery for handling units, from the number range interval '01'. Maintenance of further intervals is not necessary, as the interval cannot be set.

Transport

You transport number range objects as follows:

In the initial screen, choose Interval -> Transport.

Note that all intervals for the selected number range object are deleted in the target system first. After the import, only the intervals you export are present. The number statuses are imported with their values at the time of export.

Dependent tables are not transported or converted.

Actions

1. If the number range is not available for the interval '01', you must insert the number interval '01'.2. Enter the boundaries for the number interval. SAP recommends that you maintain the number range interval in the maximum range.

b) Choose Display interval.

2

3. Check whether unique number assignment is activated at client level.a) Choose SAP Reference IMG → Logistics - General → Handling Unit Management → External Identification → Set Up Unique Number Assignment for HU Identification.

Set Unique Number Assignment for HU Identification

In this activity, you establish that assignment of handling unit identification is unique in this client.

Example

If you want to process or display a handling unit, it is only possible to find and select it if this identification occurs only once.If you allow multiple assignment of the same handling unit identification, the system cannot determine exactly which handling unit you are requesting, thereby ruling out any chance of scanner-supported processing, for example.

Requirements

Number assignment settings must be made for all packaging material types in the Implementation Guide.

Standard Settings

The standard system contains unique number assignment.

Recommendation

If you want to use handling units outside outbound delivery processing, check the appropriate checkbox.

Activities

Check the checkbox for unique number assignment.

Further Notes

It is only possible to indicate a storage location as HU-managed if you have set this indicator.The use of non-assigned handling units without unique number assignment is not supported. In particular, a link from handling unit to storage unit is not possible if there is no assurance of unique number assignment.

b) The indicator HU ID unique is set.

3

4. Display the number range for client-wide unique handling unit identification.a) Choose SAP Reference IMG → Logistics - General → Handling Unit Management →External Identification →Number Range Maintenance for HU Identification.

Number Range Maintenance for HU Identification

In this activity, you can maintain number ranges for number assignment for handling unit identification via number range intervals.

There are two types of number assignment:

Internal number assignment

The SAP System automatically assigns a sequential number from the specified number range. External number assignment

When creating a handling unit, you use a number from the external number range.

It is possible to maintain multiple internal and external number range intervals in order to assign numbers from different intervals to various packaging material types.

Requirements

The number assignment section in the packaging material type of the packaging material must be customized for number assignment from an internal or external number range interval in order for it to take place.

Standard Settings

A delivery of an internal and external number range interval with suggested values is available.

Recommendation

When choosing your intervals, make sure that the number ranges will not overlap.

Activities

To define a number range, you must insert a new number range interval:

1. Enter an alphanumerical key with a maximum of two characters.

2. Enter the limits for the number interval. Individual number intervals may not overlap. In other words, each number may only appear once.

4

3. If the number range is to be used for external number assignment, indicate it as such.

Transportation

You transport number range objects as follows:

In the initial screen, choose Interval -> Transport.

Note that all intervals for the selected number range object are deleted in the target system first. After the import, only the intervals you export are present. The number statuses are imported with their values at the time of export.

Dependent tables are not transported or converted.

Further Notes

If you also plan to use handling units in the warehouse in connection with storage units, make sure that the maintenance for number range intervals for storage units has the same length as the intervals maintained here.

b) Choose Display intervals.

5. Display the number range for handling unit identification by SSCC. Thenumber range object has the key LE_SSCC.a) Choose SAP Reference IMG → Logistics - General → Handling Unit Management → External Identification → SSCC Generation Acc. to EAN128 → Maintain Number Range Object for SSCC.

SSCC Generation Acc. to EAN128In this IMG activity, you make the settings for generating shipping unit numbers / Serialized Shipping Container Codes (SSCC).To do this, you need an international location number (ILN) which you receive from the subsidiary company responsible for your country, from the IAN (international article number), or from the UCC in the US.Create at least one number range object that hasn't been predefined by SAP before you determine the parameters for your organizational units. If you have your own ILN for each organizational unit, you can use the whole number range in these units for the SSCC.NoteNote that the intervals can overlap and therefore the same number can be assigned twice. You must ensure for your area that the intervals do not overlap.

Maintain Number Range Object for SSCCIn this activity, you maintain the number range objects and their associated internal and external intervals for the generation of SSCCs.You need at least one object and one internal interval to create sequential SSCCs for your entire organization (client). If you want to have numbering start again from one for individual organizational units (plant, storage locations or warehouse numbers), you must create new objects. In such cases, you would also need new ILN base numbers.

Standard Settings

Number range object "LE_SSCC" is provided with interval "01" and a 9-digit number length in the standard system.

Recommendation

ILN base numbers are normally 7 digits long, although sequential numbers with 9 digits are possible within the Number of Shipping Units/Serialized Shipping Container Code (NSU/SSCC). For this reason, domain "CHAR9" is available for defining number length. Base number and sequential number must occupy 16 digits total (the entire NSU/SSCC is 18 digits in length, including check digit and type).

If the ILN base number has more or fewer digits (or if you provide individual constant suffixes), you must adjust the domains accordingly.

You can activate the main memory buffering. EAN128 standard requires exclusively unique, not sequential, numbering.

6

If you allow rolling intervals, after the first interval has been completely used up, the system automatically reassigns the first number that was originally assigned in the initial interval. The standard system does assume that the initial assignment occurred at least one year ago, however.

Activities

Create the number range objects and intervals necessary for your organization, paying special attention to the domain lengths and the length of the ILN base number.

b) Enter the object key LE_SSCC in the Object field. Choose Number Ranges and then Display intervals.

7

6. Check the assignment of the number range object, the number range interval,and the base ILN number to plant 1000.a) Choose SAP Reference IMG → Logistics - General → Handling Unit Management → External Identification → SSCC Generation Acc.to EAN128 → Maintain SSCC Generation for Each Plant/Storage Location.

Maintain SSCC Generation for Each Plant / Storage Location

In this activity, you can set all parameters for generating Numbers of Shipping Units/Serialized Shipping Container Codes (NSU/SSCCs), except for those on the storage location level.

Example

Normally, your entire organization does not create more than 1,000 billion handling units per year. Therefore, you only need one ILN from which to copy the 7-digit base number into an entry (by leaving all key fields blank: plant and storage location, for example). You have previously created a number range object with a rolling 9-digit internal interval. Now you need to assign this number range object.

If you would also like to send smaller packages and manage them with NVE/SSCCs as well, you would need more than 1,000 billion NSU/SSCCs per year. In this case, you should enter another base number and a new number range object with an internal interval. Assign these to the exact plant and storage location.

Requirements

You must have previously created a number range object and an internal interval. If you want to assign NSU/SSCCs externally and you want the system to check if they lie within the valid range, you must also create an external interval.

Recommendation

If you do not want to generate specific NSU/SSCCs for individual storage locations (and/or plants), leave the storage location (and/or plant) blank, saving you time and effort since there is less information to maintain. You may add information to the individual storage location/plant entries later on if necessary.

If the number range is not sufficient for one year (the expected time period in the standard system in which no NSU/SSCC is to be repeated), you can maintain additional parameters in the same organizational unit. The number range object may not be a rolling number range object in such a case. The system selects and entry in the field Do not use?.

Further Notes

The system searches for NSU/SSCC generation parameters in the following key order:

8

1. Plant and storage location: the most detailed of the possible structures

2. Warehouse number: maintain the parameters for this organizational unit in the next node3. Plant: the same parameters for all storage locations of one plant. Leave the Storage location field blank.4. Client: the same parameters for all plants. Leave the Plant field blank as well.Note that the intervals can overlap and therefore the same number assignment is possible twice. You must ensure for your area that the intervals do not overlap.

b) There are two entries for plant 1000.

7. Call up the Handling Unit Monitor and display the detail data for a handlingunit containing material T-K3-##.a) Choose Logistics→ Central Functions → Handling Unit Management→ Handling Unit Monitor.

Handling Unit Monitor

Use

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.

Integration

Depending on the application, you can find the handling unit overview from the SAP menu as follows:

From the SAP menu, select Logistics ® Central Functions ® Handling Unit Management ® Handling Unit Monitor.

In the SAP menu, select Logistics ® Materials Management ® Material Master ® Other ® Stock Overview. Display a material and select Environment ® Handling unit

From the SAP menu, select Logistics ® Production ® Handling Unit Management ® Repetitive Manufacturing ® Backflush ® HU Management ® Handling Unit Monitor.

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:10

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:

1. 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.

2. 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:

o 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.

o 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.

o 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.

11

o At the end of the list, the total amount (4) of HUs is taken as the fourth subtotal (****).

For example, if the material changes first (third subtotal), but the load carrier does not (second subtotal), the second subtotal is still calculated.

3. 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.

b) Choose Execute.

c) Select the handling unit and choose Display Selected HUs.
