difference between Transfer of requirement and availability check

[Former Member]

Hi,

what is the difference between transfer of requirement and availability check..

[Former Member]

Hi,

TOR : Transfer of Requirement to MRP... that is tranferring the sales requirement to Material requirement planning,.. so that MRP will plan for the required materials to be ready...

Availability check : Checking the availabilty of the material for the particular date, to give the confirmation..

hi Venkat,

Transfer of Requirements

The MRP department is informed about the quantities and deadlines by which incoming orders

should be delivered. The system checks the availability of the goods based on the requested

delivery date of the customer and creates MRP records which contain all necessary information

for passing on to planning. It ensures that the goods are available in time for the delivery.

Materials planning transfers the reported requirements and creates orders or purchase

requisitions from them etc.

When we create a sales order, there are several basic functions which are executed automatically for the dynamic order management . among these basic functions , availability check and transfer of requirements are crucial.

the system first prepares schedule line containing the information on the desired delivery date and quantities , this information is passed to MRP and an avialability check and transfer of requiremnts are executed

First the system carries out backward scheduling and establishes the material avaialbility date = desired delivery date-transit time-loading time-picking & packing time and on this date an availability check is carried out using ATP logic which means avialable to promise quanity =total ware house stock+incoing orders-outgoing

along with the avialability check the requirements also are transferred to MRP.

the configuration involves following

1. switching on at schedule line catagegory the avialability check and TOR

2. configure the avilability check using ATP and using the checking group and Checking rule

dear venkat

please gothrough this. which can give you nice explanation about TOR & Availability check

TOR AND AVAILANBILITY CHECK

To confirm the quantities for a particular line item in the sales order on particular day system carried out transfer of requirements (TOR) & AVAILABILITY check, so has to confirm the quantity on particular day as system should know what are there requirement of the sale order and delivery with MRP then system carries out availability check function, to confirm the quantity on particular day. Depending upon the IMG setting system carries out availability check function based on 3 methods:

A) Availability Check with ATP logic or against planning:

In ATP logic systems ATP Qty while carrying out availability check function for

Particular line item (ATP qty=warehouse stock +planned receipts planned issues)

Planned Receipts: EX: - purchase requisitions, purchase orders, stock in transfer stock at inspection etc.

Planned Issues: - EX: - open sales order & open delivers

B) Availability check against product allocation:

Availability check can be carried out against product allocations in which system automatically restrict the user to confirm the quantity beyond reserved quantities per particular customer. EX:- Availability qty =100, existing orders=10,then system automatically distributes to items evenly to the sales order.

C) Rule based Availability check:

Rule based availability check can be carried out based on the business transaction.

EX: - For normal sales order system has to carry out availability check for special sales order ex: - cash sales and rush order systems need not to be carry out availability check,

In rule based availability check system in which system carried out Global availability to promise in all plants. In this check system transfers the requirements to APO system where GATP takes place and the result of the availability check transferred to R/3 system. This process takes place with the transaction code CIF(central inter face) inR/3.After carrying out availability check function system proposes(by using ATP logic) default values of ATP check result to the user in a dialog box, in which system gives the choice to the user to take the decision in contest of insufficient stock.

a) One time delivery:

If the user chooses one time delivery and the order Quantity is 100 units system confirms 50 units then systems automatically confirms as a zero. If the user saves the document with the zero confirm qty then system trace the sales order as aback order (V_RA), which can be confirmed later by RESCHEDULLING (V_V2).

b) Complete Delivery:

If order Qty=100, Availability stock = 50, system says that remaining can be given after one week. Then if the user selects this option then system push up existing confirmed qty to after one week and the total qty can be confirmed after one week only.

c) Delivery Proposal:

If order qty=100, system confirms 50, and remaining 50 can be confirmed after one week. If the user chooses this option then system confirms 50 Qty today allows the user to delivery 50 quantities today remaining 50 can be delivered after one week.

CONFIGURATION SETTINGS FOR TOR:

Define Requirement Class:

Path: Img  S&D  Basic functions  Availability Check & Transfer of requirements  Transfer of requirements  Define Requirement classes

Requirement classes control MRP, Requirement consumption, strategy, relevance for planned. It specifics whether the availability check & TOR to be Called out for transactions. Ex: Sales Order

It determines whether requirements relevant for MRP or not, the allocation indicator from the sales view which controls the settlement of customers requirements with planned independent requirements. It determines the item b to be settled as an availability heck. Assignment, the settlement profiles the results analysis key. The TOR and Availability check functions are globally controlled using the requirement class for all the Sales documents. The values from the Requirements class are transferred to scheduled the of the sales documents class are transferred to scheduled the of the sales document default values and can be over written there.

Define Requirements Classes:

Requirement class defines whether the system has to carry out availability check based on the STP Qty. Ex:

Define Requirement Types:

Here we define requirement type, Ex: and Assign to Requirement class that we defined in the promote step.

Determination of Requirement types using Transaction:

Requirement type is going to be determined for sales document by following a search strategy. .

First System checks strategy group in MRP3 view if it trend requirement type then system takes from it, otherwise.

It will go to MRP group in MRP1 view, otherwise

It will check to Material type, otherwise

It will go to item Category + MRP type, otherwise

It will go to Item category only, otherwise

Finally system determines the transaction b not relevant for TOR & Availability check.

Choose Item category TAN+MRP type PD=Requirement type =0

Define Procedure for each schedule the category:

Here we define respective schedule the category of the sales documents, whether an availability check and TOR should be carried out. This setting is relevant for sales documents only. It is fine tuning of availability check for sales documents TOR & Availability check function can be activated at sales order level those are proposed in to schedule line category level. If u wants to deactivate TOR availability check function at schedule the category level and want to deactivate at requirement class level it b impossible.

Ex: If u wants to check availability w/o transferring the requirement we can use it.

Choose schedule line category CP & Activate Availability check, requirement & Product Allocation

Block Quantity confirmation in delivery Blocks:-

When we transfer requirements to MRP then confirmed quantities is also reserved for confirmed sales documents, if transaction is blocked for delivery the reserved quantities are also blocked so that the conformed quantities cannot be used by any other purpose. So has to avoid this situation we can block the transfer of requirements(TOR) for delivery blocks, in this case requirements transferred to MRP but will not be reserved, that will be cleared once we save the documents then system shows confirmed qty as zero.

When we remove the delivery block then system automatically carries out availability check & confirms the qty.

A) Deliveries: Blocking region for sales Area:

Here we define blocking regions for TOR ex:-credit limits

B) Reasons for scope of delivery blocks: TOR. Block:

Ex: - 01 credit limits-check confirmation block.

Maintain Requirements for TOR:-

Here we can define our own requirement with the help of ABAPer for TOR

Ex: - a) 102- prevent reservation in the event of credit block

b) 102-purchase requisitions.

System doesn’t create purchase requisitions for sales order line items if it has a credit limit.

Availability check:

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).

dear venkat,

Avc & tor are linked with each other.

for ex.

u have stock of X m 5.

u put order for 10.

in this case system check the availability i.e 5.

&tranfer remaning qty for prod. i.e 5 called TOR.

avaibility is based on.

checking grp which u maintain in MMR i.e 01 collective req. etc.

checking rule.

schedule line

req class

for tor it is almost ssme.

strategy grp in mmr mrp 3 view

req class

req type

schedule line

mrp type.

if need any help plz

regards

nitin
