    Types of Availability Check in Sales and Distribution


    There are three types of availability check:

    _ Check on the basis of the ATP quantities

    _ Check against product allocation

    _ Check against planning

    The following SD-specific control features need to be maintained in Customizing:

    _ Checking group

    The checking group controls whether the system is to create individual or collective

    requirements in sales and shipping processing. In addition, a material block for the

    availability check with transfer of requirements can be set here. The checking group can

    also be used to deactivate the availability check. This option was created especially for

    the assembly order so that when the bill of material is exploded in the assembly order,

    the individual components, if necessary, can be classified as non-critical parts as far as

    procurement is concerned.

    The checking group specifies in combination with the checking rule the scope of the

    availability check. It is proposed in the material master record on the basis of the material

    type and the plant, and copied into the sales and distribution documents.

    _ Checking Rule

    You use the checking rule to control the scope of the availability check for each

    transaction in sales and distribution. You also specify whether the check should be

    carried out including or excluding replenishment lead time. The individual checking rules

    define by transaction, which stock and inward and outward movement of goods should

    be taken into account for the availability check.

    _ Schedule line category

    You can control with the schedule line category whether an availability check and

    transfer of requirements should be carried out in the sales documents. The possible

    settings for this at schedule line level are dependent on the settings in the requirements

    class which is determined from the requirements type of the material.

    _ Delivery item category

    The delivery item category can be used to control whether an availability check takes

    place in deliveries.

    Requirements type

    The various requirements are identified by their requirements type. The requirements

    type refers to the requirements class and its control features.

    _ Requirements Class

    The requirements class contains all control features for planning such as relevance for

    planning, requirements planning strategy and requirements consumption strategy. In

    addition, it is specified at a global level whether an availability check is to take place for

    the material in the sales and distribution documents on the basis of the ATP quantity

    (ATP = available to promise) and whether requirements are to be passed on. A finer

    degree of control can be obtained for sales documents using the schedule line category.

    Replenishment lead time is only included in the check performed on the basis of the

    ATP quantity.


    An availability check can only be carried out if the following prerequisites have been fulfilled:

    _ The control elements described above for the availability check must be maintained in

    Customizing for Sales and the relevant assignments made to the sales transactions

    _ The availability check must be switched on at requirements class level and - for the

    availability check in the sales documents - at schedule line category level

    A requirements type must exist by which the requirements class can be found

    _ A plant must be defined. It can either be proposed from the customer or material master

    record or can be entered manually in the document.

    _ A checking group must be defined in the material master record on the Sales/plant data

    screen in the Availability check field

    Configuring entries of the Availability Check

    IMGSDBasic fncsAvailability check and TORAvailability checkAvailability check with ATP logic or against planningDefine checking groups

    You can use SAP std checking groups of 01 for summarized reqts or 02 for daily reqts or u can create ur own.

    The columns total sales and total deliveries are selection options whereby u can configure a checking rule to sum up reqts to post to MRP either individually or by day or week.

    Column 5, Block qty; set this block if u want several users to be able to process the material simultaneously in different transactions without blocking each other. The No Check indicator is used when u want a material to not be relevant for an ATP check.

    Defining a material block for other users. The Block checkbox is an indicator that enables u to block the particular material from being checked for availability if it is already being checked at the same time by another user.

    Defining the default value for checking groups. However should no entry exist for the checking group in the material master record, one can set a default value per material type and plant.

    Controlling the availability check. In this section, u tell the system what stock on hand and what inward and outward movements of stock it must take into account when performing the availability check. These settings are based on the checking group that is assigned to the material master record and the checking rule that is predefined and assigned to the sd transaction. The carry out control for the availability check must be maintained for both the sales order and delivery.

    For every item of a sales order or delivery, the SAP system checks availability if the appropriate configuration is set in sales order processing and shipping. The availability check procedure depends on several factors and varies according to the configuration.

    It is possible to control the availability check for sales documents and deliveries separately. You can,for example, control the scope of the checks or whether the replenishment lead time is taken into account, for example.

    The availability check is controlled by means of the same elements as the transfer of requirements:

    Requirements class

    Requirements type

    Checking group

    Checking rule

    Schedule line category

    Strategy group

    Planning strategy

    For more information on strategy groups and planning strategy, see the 'Planning strategy' chapter under Production Planning in the Implementation Guide.


    Process the following points to control the availability check:

    1. For the sales document types you must determine for each schedule line type whether an availability check should be carried out or not.

    2. The availability check should be switched on at requirements class level and at schedule line level for sales documents.

    3. You can define a checking group which can be proposed, depending on the material type, when a new material master record is created.

    4. The requirements types used must each be allocated to a requirements class.

    5. Note that a plant must be available if an availability check is to be carried out at document item level
