Differences

Hello All,

Can someone explain the difference between "Transfer of requirement" and "Availability Check". Why do we create both of these for Sales document.

An example would be great.

Thanks,

Gauravjit.

Hi

Availability check means when a sales order is created the system checks whether the material is available so that it can confirm delivery for requested delivery date

If sufficient stocks are available in unrestriced stocks then it confirma the delivery

It all depends on the setting done in OVZ9 for checking rule and checking group combination

If the product is not available then the reqiirement is transferred TO MM area through transfer of requirements so that MM peopple can procure the material

This happens through the settings IN VOV6

First it is Availability check and then it isTransfer of requirements if material is not available

For all these SPRO settings has to be done

If Transfer of requirements is active then in MD04 which is a mm area t code the mm people can see your sales order and plan to make the materials available

hi,

ATP is known as available to promise quantities and it is

calculated as below.

Ware house stock + planned receipts ? Planned issues = ATP

quantities.

Ex1. 100 + 50 -75 = 75 is ATP Quantity

Any remaining open quantity in the movement is regarded as

the ATP quantity and can be used to fulfill the next

requirement.

Ex2. 25 + 100 -150 = -25 ATP Quantity,

In this case the system try to capture the stock from other

inward movement and try and match the order quantity 150.and

even this is not available and partially met then the system

shows the negative ATP Quantities in the requirement line.

During the availability check the system determines the

ATP quantities for the material and the pant.

The system behaves in performing the availability check

based on how the availability check is set in customizing.

This can be viewed in the sales order. over view screen procurement and you can see the confirmed quantity and ATPQuantity.

Availability check:

Stock checks which is automatically carried out after every

goods movement and which should prevent the book inventory

balance of physical stock (for example, available stock)

from reaching zero.

types of Availability checks

1. Against ATP

2. against product allocation

3. Against planning.

Availability check is based on checking group, Requirement

class, and Requirement type and schedule line category.

Hi

I have tried to explain you with simple language and never used CTRL C and CTRL V anywhere

If enough stocks are there even then reqirement transfer will happen for that material depending on the controls you have defined in MRP 1 and 2 tabs of material master

MRP is material requirement planning

MM is material management where as our collegues will be configuring

Availability check and TOR is MM area too which you wii closely coordinate with MM during implementation

I did not intent to direct about copy and paste at anyone but was a general statement.

I wish i had the option of deleting the post/s which i feel is not relevant to my queries. or better still give negative points

This would help everyone in long run, as i think that most of the people seeking help here would have gone through the sap help before turning to SAP Experts here.

Thanks

Gauravjit.

PS: The view expressed above are my personal views.

Hi..

1) The following SD-specific control features need to be maintained in Customizing:

_ Checking group

The checking group controls whether the system is to create individual or collective

requirements in sales and shipping processing. In addition, a material block for the

availability check with transfer of requirements can be set here. The checking group can

also be used to deactivate the availability check. This option was created especially for

the assembly order so that when the bill of material is exploded in the assembly order,

the individual components, if necessary, can be classified as non-critical parts as far as

procurement is concerned.

The checking group specifies in combination with the checking rule the scope of the

availability check. It is proposed in the material master record on the basis of the material

type and the plant, and copied into the sales and distribution documents. It is specified in MMR in MRP3 screen, availability check tab.

_ Checking Rule

You use the checking rule to control the scope of the availability check for each

transaction in sales and distribution. You also specify whether the check should be

carried out including or excluding replenishment lead time. The individual checking rules

define by transaction, which kinds of stocks and inward - outward movement(receipts and issues) of goods should

be taken into account for the availability check.

_ Schedule line category

You can control with the schedule line category whether an availability check and

transfer of requirements should be carried out in the sales documents. The possible

settings for this at schedule line level are dependent on the settings in the requirements

class which is determined from the requirements type of the material.

_ Delivery item category

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

place in deliveries.

Requirements type

The various requirements are identified by their requirements type. The requirements

type refers to the requirements class and its control features. it is assigned to requirement class.

_ Requirements Class

The requirements class contains all control features for planning such as relevance for

planning, requirements planning strategy and requirements consumption strategy. In

addition, it is specified at a global level whether an availability check is to take place for

the material in the sales and distribution documents on the basis of the ATP quantity

(ATP = available to promise) and whether requirements are to be passed on. A finer

degree of control can be obtained for sales documents using the schedule line category.

Replenishment lead time is only included in the check performed on the basis of the

ATP quantity.

Prerequisites

An availability check can only be carried out if the following prerequisites have been fulfilled:

_ The control elements described above for the availability check must be maintained in

Customizing for Sales and the relevant assignments made to the sales transactions

_ The availability check must be switched on at requirements class level and - for theavailability check in the sales documents - at schedule line category level

A requirements type must exist by which the requirements class can be found

_ A plant must be defined. It can either be proposed from the customer or material master

record or can be entered manually in the document._ A checking group must be defined in the material master record on the Sales/plant data

screen in the Availability check field

Configuring entries of the Availability CheckIMGàSDàBasic fncsàAvailability check and TORàAvailability checkàAvailability check with ATP logic or against planningàDefine checking groups

You can use SAP std checking groups of 01 for summarized reqts or 02 for daily reqts or u can create ur own.

The columns total sales and total deliveries are selection options whereby u can configure a checking rule to sum up reqts to post to MRP either individually or by day or week.

Column 5, Block qty; set this block if u want several users to be able to process the material simultaneously in different transactions without blocking each other. The No Check indicator is used when u want a material to not be relevant for an ATP check.

Defining a material block for other users. The Block checkbox is an indicator that enables u to block the particular material from being checked for availability if it is already being checked at the same time by another user.Defining the default value for checking groups. However should no entry exist for the checking group in the material master record, one can set a default value per material type and plant.

Controlling the availability check. In this section, u tell the system what stock on hand and what inward and outward movements of stock it must take into account when performing the availability check. These settings are based on the checking group that is assigned to the material master record and the checking rule that is predefined and assigned to the sd transaction. The carry out control for the availability check must be maintained for both the sales order and delivery.

TOR

IMG à SD à Basic fncs à Availability check and TOR à TOR

A line item in the sales order creates a schedule line. The schedule lines in the sales order transfer the requirements through to MRP. You can select the docs on which you want the TOR to happen. For ex, not for quotations.

The TOR aims to ensure the ordered materials are available for the requested delivery date. The TOR can be set for individual or for collective requirements (materials masteràsales/plant view).

The TOR is dependent on the following data:

The reqts type, reqts class, checking group and schedule line category.

The reqts type and class are determined in the strategy group (material masteràMRP3)

For TOR to be carried out, a few criteria need to be met:

Plant assigned to line item level, schedule line category should be switched on at TOR, TOR must be switched on at the reqts class level, checking group must be defined and allocated to the material master record (sales/plant view in the availability check field)

The reqts class is the controlling factor for the availability check and the TOR for all sd types.

Configuring the TOR:

1) Use std 041 reqts class or copy and rename it. Use the indicators to select if this reqts class must carry out an availability check and/or a TOR.

2) Define the reqts types. A reqts type is allocated to a single reqts class and not vice versa. It is based on the item category and the MRP type of the material.

3) Assign the rqts type to the relevant item category in the sales order and the MRP type found on the material master record.

You can select an alternative search strategy where u assign the reqts type to item category and MRP type. Can select source as 0, 1 or 2. (1 = Item type and MRP type strategy).

4) The TOR and Availability check can be selected/de-selected at the schedule line category level.

5) Block qty confirmation in delivery blocks. This is used to block the reservation of the TOR from MRP.

6) Maintain requirements for TOR. Requirements can be used to determine that the TOR to MRP is not carried out unless a number of conditions are met.

Availability Overview = CO09 à order qty, sd doc no, item no, requirements class.

Stock requirements list = MD04 à sd no or dly no, line item, schedule line placing the demand

Stock overview = MMBE à total stock per company, then plant followed by storage location, and finally a breakdown per batc

Hi

MD04 is Stock requirement list which MM people are supposed to view for a material so that so see SD requirements and arrange for stocks

If you have the system see this t code and it will be clear to you

I am not able to get what do you mean by real time examples?

If the settings are done as per my earlier post then you can see your order in MD04

In VOV6 there are two check boxes intransaction flow tab availability and req/assembly

This triggers availabilty check and transfer of requirements

In -IMg-s.d-basic functions-availabilty check and transfer of requirements in that you see all the activitites

All your queries wii get cleared

Real time example....are the one which are real scenerio example rather than copy and paste from help.sap.com.

Trying to understand the difference...

Are we saying that in case there is no availability...then only the requirements are transferred...or it it for all sales transaction.

Another thing i don't understand...what is the meaning of MM people...isn't it good to have knowledge of the integration area rather than be dependent on someone else.

Dear Gauravjit

Crisp explanation is

Transfer of Requirements

Once you create a sale order, the requirements will be passed on to MM / PP to enable them procure components, produce components.

Availability Check

Depending upon the scenario, (Make To Stock or Make To Order), your availability check will happen in sale order. That is stock will confirm while you create sale order and give a delivery date.

thanks

Read somewhere TOR is at global level whereas Availability check is at lower level.

Trying to figure out this statement.

Someone pointed out that in case the stock is not available, the requirement will be transferred to MM/PP and it can be checked via MD04, but isn't it that in MD04 we can view even the sales orders which are still open...

What does MD04 transaction is for....

Can someone help me understand

1. As to how TOR and availability check is linked

2. Is TOR and Avail check always checked for together [for what kind both are checked and for what kinda we don't...real time example would be great.

Regards,

Gauravjit.

Good posts with real example would be rewarded.
