Regarding tranfer of requirements

[Former Member]

Hi to all,

can anyone please tell the processs of How the system performs availability check from sales order. what are all the configuration settings required in spro and in terms of mater data. How it will triger MRP

ATP

Types of Availability Check in Sales and Distribution

Processing

There are three types of availability check:

_ Check on the basis of the ATP quantities

_ Check against product allocation

_ Check against planning

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.

_ 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 stock and inward and outward movement 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.

_ 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 the

availability 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 Check

IMGSDBasic fncsAvailability check and TORAvailability checkAvailability check with ATP logic or against planningDefine 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  SD  Basic fncs  Availability check and TOR  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 mastersales/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 masterMRP3)

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  order qty, sd doc no, item no, requirements class.

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

Stock overview = MMBE  total stock per company, then plant followed by storage location, and finally a breakdown per batch.

HI SRIRAM,

CAN U TELL ME THE DIFFERENCE BETWEEN

requirement class- Requirement class level

schedule line category - schedule line level

I am new to basics

hai,

Transfer of requirments:

for TOR to happen the folowing control elements must be defined

1. requirmrent type.

2.requirement class.

3.checking group

4.schedule line category.

apart from the above the TOR must be switched on at

1.reqt class level.

2.schedule line level

3.checking group level.

4.plant must defined at the document item level

once order is raised the requirments are transfered from order to MRP by TOR,

various reqts are identified thru reqt type, reqt type are identified in the system thru

1. strategy group--MRP1 --mmr

2.MRP group.

3.material type.

4. ITEM category +mrp type

5.item category

once reqt type is identified it points to reqt class.

reqt class contains all the control factors suchas planing strategy,consumption strategy etc

basing on the item category group+ mrp type-- schedule line categories are identified.

if it is relevant for availability check, then the system does ATP CHECK(warehousestockplanned ordersproduction ordersconfirmed receiptsconfirmed goods issues) and decides whether goods are availabile on

the requested delivered date of the customer, if not system does a backward scheduling and confirms when material is available (materual availability date),

so if material is not available then system proposes 2 dates

1.customer delivery date

2.material availability date.

for availability check to happen the following pre-requistes must be there:

1.availability check must be swithched on at the requirment class level

2.schedule line level itmust be switched on

3.reqt type must be defined

4.checking group must be defined.

5.plant must be defined

6. the system takes by default checking group if not defined as material type and plant.

from SD the following componenets are importants

1.checking group:defines whether indivual orcollective req are to be passed

2.checking rule: defines scop of the check(what type of stock+with or without RLT)

3.schedule line category: this fine tunes whether availability check should be carried on at the sales document level or not.

4. delivery item category.

for config:

SPROSALES&DIST-BASIC FUNCTIONS--TOR&AVAILABILITY CHECK.

In material master the below mentioned must be defined also

1.strategy group.

2.scheduling margin key.

3.in house production time.

4. RLT time.

5.MRP group

reward points!!!!!!!!!!!!!
