Hi,

There are three types of Availability check explained as under:

ATP basis check

Available To Promise (ATP) is calculated from warehouse stock, planned inward movement of stock (purchase orders, planned orders etc.) & planned outward movement of stock (sales orders,

deliveries, reservations etc.)

.

Check against Product Allocation

Product allocation is used for period based distribution of products for specified customers or regions. This check is over the normal availability check. It is carried out in cases where production is low and goods produced need to be distributed to customers and ensured that first customer is not allocated complete quantity.

Check against Planning

Check against planning is performed against planned

independent requirements which are generated from a demand planning program.

ATP check Including RLT

Availability check is calculated only up to end of RLT. If the material availability date calculated on basis of current date lies after RLT, system confirms the item in spite of insufficient stock in the assumption that stock would be procured or produced by that time. Thus confirmation can be sent to customer in this

case.

ATP check Excluding RLT

If RLT is not included in ATP check system performs a check on the unrestricted stock and scope of check on inward and outward movement of stock.

Control Parameters of Availability Check in Sales

Following SD specific control parameters need to be maintained.

 Checking Group

Checking group forms one of factors for specifying scope of availability check. It is used for grouping of materials for individual or collective requirements. It is assigned in material master Sales/Plant view.

 Checking Rule

Checking rule forms the other factor in specifying scope and is assigned to each transaction in sales and distribution. The checking rules are predefined in system.

 Schedule Line Category

Schedule line category had additional check to turn on/off availability check.

Delivery Item Category

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

in deliveries. This setting in the availability check is used to switch the availability check off

in deliveries.

Requirements Class

The requirements class as used in the transfer of requirements controls the relevance for

planning, requirements planning strategy, and requirements consumption strategy. It is also

responsible to determine if an availability check is to be performed for the material on the

basis of the ATP quantity and whether the transfer of requirements is passed on.

Requirements Type

The requirements type refers to the requirements class and its features. The requirements

class is assigned to the requirements type in the transfer of requirements.
