    Hi

    For every material movement, the system automatically performs an availability check of the stock types if this has been defined for a material. The availability check prevents the book inventory balance of the various physical stock types (for example, unrestricted-use stock) from becoming negative.

    If several withdrawals of material are entered in a single document (for example, for different account assignments), the system checks the availability of the material for each item entered. It checks whether the desired quantity can be withdrawn. The system takes into account those items of the document that have already been entered, but not yet posted.

    If there is not enough stock to cover the withdrawal, the system issues an error message.

    The availability check includes the stock in question at plant, storage-location, and special-stocks level, for the current month and, if necessary, for the previous month. Different stocks are checked, depending on the movement type:

    In the case of a withdrawal for consumption, unrestricted-use stock is checked.

    In the case of a release from stock in quality inspection, quality inspection stock is checked.

    In the case of consumption of consignment material, consignment stock for unrestricted use is checked.

    Hello,

    Production

    The availability check in Shop Floor Control checks whether the components, production resources/tool or capacities required for a production order are available.

    Shipping

    Few reasons to carry out Availability Check in Sales

    If you carry out Availability check in sales order you should definitely check whether the order quantity is available and can be delivered when you create the delivery.

    It is calculated using planned inward and outward movements of goods

    The system determines the date on which the availability check should be carried out on the basis of the earliest material availability date of all the schedule lines in the delivery. If the system determines that insufficient stock will be available on that date, it responds as follows:

    If a material is not available for delivery by the material availability date, the system enters a delivery quantity of zero in the delivery. The item is only included in the delivery if the quantity zero is permitted for the item category.

    If the quantity available of a material is lower than the order quantity, the system enters the available quantity as the delivery quantity. If a partial delivery is not allowed for the sales order, the fact that the delivery quantity is smaller than the order quantity is noted in the log for the delivery.

    Please reward if found usefull.

    Dear Murunga,

    There are two types of availability checks

    1)Availability Check for stock types in Inventory Management ( Static Availability Check):

    This check takes only the existing stock at the time of entry into account.This check is carried out automatically & no setting can be made for it in the system .It covers the relevant stock affected at the plant , storage location & special stocks level.The stock affected are determined via the movement type.

    Ex: If you enter tranfer posting with mvt 321 for 20 nos from Quality to unrestricted the system checks whether 20 nos.are actually available in Quality stock

    2) Check of vailable stocks from the view point of MRP ( Dynamic availability check):

    In this case in addition to stock physically available in warehouse , here planned receipt & issues can also be taken into account.This check enables you to prevent an already reserved quantity from being withdrawn Or reserved for another purpose.

    For Ex; Today we have a stock of 100 nos. 25 pieces are reserved for withdrawl tomorrow & another 25 nos are reserved for day after tomorrow which means only 50 pieces are available today.If you try to create another reservation of 60 nos today system will give warning or error message.

    I hope this will give you Idea.reward suitably.

    already enogh info is given above

    i would like to add to this that

    DAC is combination of 3 things

    1 checking rule

    2 tcode for the cheking rule

    3 checking rule assigned to the material master

    now th e moment u want to issue the goods from mb1c

    if a checking rule is assigned to this t code system is going to check whether stock is avilable or not even if stock is avilable whether there is a reservation done or not for that quantity

    now question is how the system is going to do that

    answer is

    first system calculates the avilable stock by adding up these things(depends upon how u have customized that rule in back end)

    stock in unrestricted + stock in transit + stock in quality + palnned gr + po = total avilable stock

    total stockto be issued = reservation for issue + independent requirement + dependent requirement + sales order
