Hi

Basically, Availability check is of 3 types.

Those are,

Check on the basis of the ATP (Availability to promise) quantities.

Check on the product allocation.

Check against planning.

On the basis of ATP, system takes into consideration, the warehouse stock, all inward movement of goods ( purchase order, Planned order, Production order) and all outward movements of goods (Reservations, Sales orders) with or without replenish ment lead time.

Planned independent requirements are not considered.

Hi,

Availability Check:- Availability Check in SAP is determining if the desired delivery quantity can be met on the requested delivery date.

Available to Promise [ATP]: The ATP quantity is calculated from the warehouse stock, the planned inward movements of stock (production orders, purchase orders, planned orders) and the planned outward movements of stock (sales orders, deliveries, reservations).

There are three types of availability checks in SAP.

1. Check against ATP quantities

2. Check against product allocation

3. Rule based Availability Check

Check on the Basis of the ATP Quantities: This type of check is performed dynamically for each transaction, taking into account the relevant stock and planned goods movements with or without replenishment lead time. Planned independent requirements are not taken into account here.

Check against Product Allocation: This type of check is based on certain predefined distribution quantity of products to Customers. Product allocation facilitates period-based distribution of products for certain customers or regions. This ensures, for example, that when production is low, the first customer does not get the full amount, resulting in following sales orders not being confirmed or being confirmed far too late.

Rule based Availability Check: Rule based Availability Check is based on certain rules like carrying out an availability check in several plants and with several alternative materials. This availability check takes place in the stand-alone APO planning system (Advanced Planner and Optimizer) from SAP.

Availability Check Including Replenishment Time: Replenishment lead time is only included in the check performed on the basis of the ATP quantity. Availability is only checked up to the end of replenishment lead time. If the material availability date is calculated on the basis of the current date to lie after the replenishment lead time for the item, the item itself can be confirmed despite insufficient stock being available. In this case, the system assumes that any quantity requested by the customer can be procured by the material availability date and considers the goods to be available.

hope this will provide you an overview of your queary.

with regards

Vivek.
