I am still not clear about the answer / explanation to this question -

Back order processing not possible for Collective requirements (e.g. checking group = 01 Daily req., back order process is not possible).

Could you please explain? (with a business example)

Hi

Go to tcode OVZ2 and read the documentation (F1) for field RelChkPlan. The blank is 'no check'

this is the area whr avilibility chk 01 & 02 controlled ..just see the fields ...

thank u

Manas,

I have read the F1 help pertaining to the fields you have mentioned (before also, when Eduardo suggested it). But still it is not clear to me.

Furthermore, for all the checking groups (e.g. for 01, 02 etc. etc.) this field has value blank.

So, please explain, in more detail.

Hi TW.

Sorry by the late reply. I've done some experiments without much success, so, It's also confusing for me, because until I know, you need to link it to PP, MM and so on, but I believe it's related with MRP, APO (that I don't know) and ATP with BOM, for instance, SO related with PP orders, subcontracting PO and so on).

The question, as I understand is if the ATP is linked to the availability of components in BOM. Other thing is if system has the capability for checking capacity and so on, because you can have enough components but perhaps you don't have capacity in your plant for doing it (for instance PM orders and some routes are locked). As you can read in the next links and note, it's an area with a lot of implications in integration with other modules. If somebody have other ideas, they are welcome. And if you discover something useful, please let us know.

In the other hand, see SAP Note 549064 - FAQ: Rescheduling and backorder updating in R/3, and related notes, it's very useful, specially question 2 and a report SAP suggest to use a template if you are not using APO.

I hope this helps you (I am afraid it confuses you).

Regards

Dear,

Checking Group 1 - Individual Requirement

Checking Group 2 - Collective Requirement

Always in individual requirement ,we need to manufacture/procure ( From vendor ) the goods based on Customer Order .In this case ,we doesnt have stock as ready for delivery .when a movement customer is given Order then we will start to manufacture or procure that material from vendor side to delivery the goods for customer requested delivery date .

So,for Checking Group 1 doesnt have Back order Process .

Note : Please have look into below thread .

If you have any doubts please let me know .

Thanks,

Naren,

Your post is not clear to me!

Could you please help -

1.

Checking Group 1 - Individual Requirement
Checking Group 2 - Collective Requirement

In SAP

01 = Daily requirements

02 = Individual requirements

2. Checking group dictates how (combined or separate) the requirements are passed to the other department (which is responsible for getting the material available, to be sent to the customer).

Could you please explain why with daily requirements (01) back order processing is not possible?

, , members could you please help?

Side comment: I have checked Google but I am unable to find a clear and to-the-point answer.

[former_member182378]

Manas,

i hav to mug this thing 

In my opinion you do not have to memorize anything with out clear understanding.

Simply by memorizing (the configuration or the definitions etc.) would not help you, during your explanation of the concepts during the interviewers or during your discussions with clients or colleagues.

Focus on clear understanding (with the help of simple business example).
