    hi,

    AVAILABILITY CHECK:

    Availability Check is an integral part of the business process. It determines if the desired delivery quantity can be met on the desired date. The availability check takes into account the respective activities that must be carried out before a delivery can take place. This includes the scheduling for picking or packing times & the time taken to produce or obtain the material as well as many other background functions

    SPRO- IMG- SD- Basic Functions- Availability Check & TOR- Availability Check- Availability Check with ATP Logic or Against Planning.

    Backorder Processing: is the processing of a backorder, which in itself is a sales order that has not been confirmed in full or not confirmed at a certain delivery date.

    Rescheduling: is a proposal of how confirmed quantities already assigned to sales orders can be reassigned to other orders that have a higher priority, such as an earlier delivery date.

    ATP: stands for Available to Promise. It is the process of checking the available quantities of a material. The ATP quantity is equal to warehouse stock plus the planned receipts (incoming stocks). ATP takes in to account all movements into and out of the warehouse. If selected, it can check the stock examined for ATP that can be safety stock, stock in transfer, stock in quality inspection, & blocked stock, although the planned receipts & planned issues of the stock associated with ATP may be purchase orders, purchase requisition, planned orders, prodn orders, reservations, dependent reservations, dependent requirements, sales requirements & delivery requirements.

    Replenishment Lead Time: (RLT): is the time needed to produce the requested stock. It can be the time taken by the business to produce a material or the time taken to externally procure the mat from vendor. This includes goods receipting time. RLT is only used when doing an ATP check. The value of the RLT for a material is specified on the MMR record.

    • The RLT for an externally procured material. This is determined based on the total of the processing time for purchasing, the planned delivery time & the goods receipt processing time. These setting can be made on the Purchasing & MRP 2 view of the MMR.

    • The RLT for an internally procured material. This is based on the in house prodn time, found in the MRP 2 view, & the goods receipt processing time or alternatively on the total replenishment lead time, which is found in the MMR on the MRP 3 view.

    • If a sales order is created, there is no available stock, and the ATP check is set to include RLT, the system will automatically confirm the desired quantity for the end of the RLT based on whether the material is externally or internally procured. It will still give a confirmed date according to the end of the lead-time. Should there be partial stock available, the system will confirm this partial stock available, the system will confirm this partial qty and move the remaining qty to the end of RLT. Thus it does not do an availability check outside RLT. If the RLT is three days for a specific material, it will not do an availability check outside of those three days, as it automatically thinks that it will definitely have the stock on the fourth day.

    .........

    Availability check can be configured both at requiremnt class and at the schedule line categories level.

    Whilst the availabilty check at the requirement class level via global and mandatory configuration the schedule line catgry availability check deals with the order.

    It is mandatory that the reqmnt class is flagged off for avlblty check and the schdelu line cat need not be.

    The following are the mandatory for Availability check to happen--

    1. Must be swithced on at the requirment class level and at the schedule line level.

    2. Reqmnt type must exist by which a requiremnt class can be found

    3. There must exist a plant and is defined

    4.Checking group must be defined in Material Master records(it controls whthr the system is to create individual or collective reqmnt)

    A combination of checking gropup and checking rule will determine the scope of availbaility check.

    Following are the configuration parameters:

    1. Define Checking Groups

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Checking Groups

    You define checking groups with which you specify the type of requirements records the system is to create when processing sales orders or deliveries

    2. Define Material Block for Other Users

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Material Block for Other Users.

    3 .Define Checking Groups Default Value

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Checking Groups Default Value.

    4. Carry out Control for Availability Check

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Carry Out Control for Availability Check.

    5. Define Procedure by Requirements Class

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Procedure by Requirements Class.

    6. Define Procedure for Each Schedule Line Category

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Procedure for Each Schedule Line Category.

    7. Determine Procedure for Each Delivery Item Category

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Determine Procedure for Each Delivery Item Category.

    8. Checking Rule for Updating Backorders

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Checking Rule for Updating Backorders.

    9. Define Default Settings

    Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Default Settings.

    ...........

    Availability check (ATP check) is used to check whether a product can be confirmed in a sales order, based on the fact that enough stock is available or can be produced or purchased on time. The product is reserved in the required quantity, and ATP requirements are transferred to production or purchasing.

    You can also carry out availability check in simulation. This is called availability information.

    dear aguest

    Configuration setting:-

    Availability check with ATP logic or against planning:-

    A) Define checking group:

    Checking group defines what kind of requirement record system use to create when sales order & deliveries are processed for this material. We can create 2 kinds of requirements records

    Individual requirement records: that means system creates requirement record for each S&D document.

    Summarized requirement Records: That means system creates requirement records under certain condition in the material master record. There are 2 type of summarized requirement record:

    Summarized requirement records for each day.

    Summarized requirement records for each week

    Define checking Action;

    Here we define 01- daily requirement -B 02- Individual requirements -A

    Where B-total record per day

    A-single record per day

    B) Define material Block for other users:

    When 2 users tries to confirm the quantities for the sales order for same material at a time system will be confused to confirm the quantities both sales orders. So has to avoid this kind of situation we can block the materials from confirming the quantities for 2 users at a check, check block

    C) Define checking group default values:

    Checking group is going to be determined depending upon the material type & plant.

    -Go to new entries, specify material type, ex;-FERT

    & plant = checking group of availability check: 02

    D) Carry out for Availability check:

    Here we define checking rule for the Availability check & allocate them to the checking group. The checking rules specify the scope of the availability check. For a respective transaction, means which planned receipts & planned issues systems has to taken into consideration and also it determines whether system has to take RLT into consideration.

    *Select checking group of availability check-02, checking rule=01

    *Go to details icon, & check which planned receipts & planned issues system has taken into consideration for availability check

    *save it, exit.

    E) Define procedure by Requirement class:

    Here we define requirement class whether on availability check & TOR should be carried out the setting that we carries out at requirement class level they are at global level. There settings automatically copied into define from of requirement class and vice versa.

    *Choose requirement class: 041 & check availability check & TOR (requirement)

    F) Define procedure for each schedule line category:

    Here we carry out fine tuning setting for availability check at schedule line category level. Here we define whether system has to carry out Availability check for particular transaction.

    Ex: - if we want to implement availability check w/o TOR for a particular transaction. According to settings at requirement class level TOR & availability check function activate & those setting will be copied into the schedule time category by default, so that at schedule line category level we deactivated TOR

    G) Determine procedure for each Delivery Item category:

    Here we switch on or switch off availability check functions of a delivery item category

    *choose item category ‘TAN’. & specify the appropriate value.

    H) Checking group for updating back orders:

    Here we assign checking group to a plant that rule specifies for individual application, according to which the availability check is carried out;

    I) Define Default settings:

    Here we define the result of the availability check.

    *Choose your sales Area, & check fixed dates& Qty options & specify ‘D’ or ‘E’

    Where: D- Dialog box in the case of shortages (one time delivery)

    E- Dialog box in the shortages (delivery proposal).

    rewards if it helps
