    To understand characteristics

    Characteristics:Describe the properties of objects

    Class: Grouping objects together is done by defining classes according to some defined criteria (all articles which belong to the category ).

    Characteristics

    In this step, you create characteristics for a release procedure with classification.

    Classification characteristics constitute the criteria for a release condition. If the criteria of a release condition are satisfied, the associated release strategy is assigned to the purchase requisition.

    Example

    Release condition for release strategy BA:

    Characteristic Characteristic value

    Total value of requisition Above $10,000

    If the total value of a purchase requisition exceeds $10,000, release strategy BA is assigned to the requisition.

    Requirements

    In communication structure CEBAN, you will find all the fields that can be used as characteristics for a release condition (e.g. MATKL for the material group and GSWRT for the value of the item).

    Check which fields you wish to use as characteristics for your release strategy. To do so, choose Tools -> ABAP Workbench -> Development -> Dictionary, enter CEBAN in the Database table field, and choose Display.

    Activities

    1. Create a characteristic for each field from communication structure CEBAN that is to be a criterion for your release strategy. You have a free choice of names for the characteristic.

    2. Specify the table name and the field name on the tab page Additional data (e.g. table CEBAN for field GSWRT).

    Note

    Do not select any of the indicators in the area Procedure for value assignment on the tab page Additional data. Only if none of these indicators is selected can you assign a value or value interval to the characteristic when defining your release strategy.

    When you create a characteristic for a currency-dependent field (e.g. GSWRT), a box appears in which you must enter the currency for this value. The system then converts the currency of the requisition into this currency.

    3. Check the data for the chosen field on the tab page Basic data.

    If you wish to enter several values or value intervals for a characteristic, select the Multiple values indicator in the Value assignment area.

    Note

    Value intervals can only be specified for numerical values, e.g. an interval of $10,000 to $15,000 for the value of a requisition item.

    4. Check the texts for the field on the tab page Descriptions.

    5. You can maintain default values for a characteristic on the tab page Values.

    If you maintain values here, they will be displayed as input help underCreate Procedure with Classification -> Release Strategy -> Classification. If you want to use not only the values from the input help but also other values, you must select the Additional values indicator.

    Note

    You can also specify ' ' as a default value. For example, for account assignment: ' ' for stock material, 'k' for cost center, and 'a' for asset.

    6. If you want to restrict the use of a characteristic to certain class types, specify the relevant class types on the tab page Restrictions (e.g. class type 032 for the release strategy).

    Further notes

    Further information about characteristics is available in this Customizing activity via Help -> Application help.

    Customer exits

    The following customer exits enable you to change the communication structure for determining the release strategy for purchase requisitions:

    M06B0002 - for item-wise release

    M06B0005 - für overall release

    Classes

    In this step, you create classes for a release procedure with classification.

    In a class, you group the characteristics that are to constitute a release condition for a release strategy. In the step " Set up Procedure with Classification", you assign this class to the release procedure.

    Activities

    1. Create a class of class type 032. You have a free choice of names for the new class (e.g. REL_PREQ for the release of purchase requisitions).

    2. Assign a description for the new class on the tab page Basic data.

    3. You can view an error message if different characteristics with identical values have been assigned to a class. To do so, select the Check with error message indicator in the area Same classification.

    4. If appropriate, maintain search terms for your class on the tab page Key words.

    5. Assign your characteristics to the class on the tab page Characteristics.

    Further notes

    More information on classes is available in this Customizing activity via Help -> Application help.
