Availability check.

1. Activate TOR and AC at requirement class level – OVZG

2. Define requirement types and assign requirement class to Requirement

type - OVZH



It is important to remember that a requirement type can have only onerequirement class assigned to it, whereas a requirement class can be assigned tomultiple requirement types.

What is Requirement type?

Wheather it is daily requirement , individual requirement, No requirement etc..

3. Determination of Requirement types using transaction (set up

determination rule for TOR - OVZI)

Here SAP tries to determine the requirement type using:

A. Strategy group from material master

B. else MRP group from material master

C. else Material type from material master

D. else Item category & MRP type

E. else Item category

F. if any of these above combination is not found, system treats the

transaction as not relevant for availability check and TOR



4. Activate TOR and AC at schedule line category.-OVZ8

To activate TOR and AC at schedule line category the combination of

Item category + MRP type should be available in VOV5.

Then we can activate it at schedule line category in this transaction by tickingthe AC and TOR. This particular step also controls the availability check and TOR

to the particular sales document type. If we do not want the sales doc. Type to

be relevant for the AC or TOR then we can as well switch it off at this level.

5. Define checking group - OVZ2

This is an important controlling element for TOR. Checking group whether the

System should generate the individual requirement or collective requirement.

If the AC or TOR is required at all or not. Till this 5th step is relevant for TOR &

AC



6. Define scope of Availability check - OVZ9

If we tick mark at Replenishment lead time, means our system is not sure when

we are going to receive stock and replenishment time is not mentioned. So

whatever the orders are not honoured will go into Backorders, which can be seen

in V.15 and we can process from there once the plant receives stock from

external sources or production. I have ticked it to see if my orders are going to

Back orders.



Fine tuning the AC and TOR:

7. Define checking group default values- OVZ3

8. Define the default availability check rule for sales area- OVZ J

9. Define the material block for other user-OVZ1



(We have 2 blocks placed in AC and TOR at OVZ1 and OVZ2 (define checkinggroup).

Ovz1 is a soft block which blocks only confirmed quantities but where as

Ovz2 blocks the material completely, and will not allow the user to touch till

It is saved.

10. Creating a block quantity confirmation in delivery block OVZ7

In this scenario, if the order is blocked because of credit limit, in such case the

Material will be blocked forever, if it is not release or the order is not release,

To avoid such situation, we can specify the def. period as no: of days within

which,

If the order is not release the material qty will be added to restricted stock.



11. Maintain a user define requirement for AC and TOR OVB8

If user has any special requirement that we can assign here by using ABAP

coding.

12. Define the procedure for each delivery item category. OVZK

For e.g.: Return item category REN doesn’t need any AC, so you can switch it

off here.

13. Checking the rule for updating Backorder. OMIH



If you are not able to see your plant at OMIH then probably you need to do the

following:

SPRO - Production - Material Requirements Planning - Plant Parameters - Carry

out Overall Maintenance of Plant Parameters -

Then select:

CreateEnter your plant

Check Rule: Backorder

In Short:

1. Activate AC and TOR at Requirement class - OVZG

2. Define Requirement type and assign Requirement class to it - OVZH

3. Determination of Requirement type using transaction - OVZI

4. Activate AC and TOR at Schedule line level – OVZ8

5. Define checking group – OVZ2

6. Define Scope of A.C heck – OVZ9

For fine tuning:

7. Define checking group default values – OVZ3

8. Define the default availability check rule for sales area- OVZ J

9. Define the material block for other user - OVZ1

10. Creating a block quantity confirmation in delivery block - OVZ7

11. Maintain a user define requirement for AC and TOR - OVB8

12. Define the procedure for each delivery item category – OVZK

13. Checking the rule for updating Backorder - OMIH
