Requirment class & Procedure for each schedule line category

[Former Member]

Hi all,

In requirment class we have a switch on/off indicator for avai check and TOR.In define procedure for schedule line category also we have the same.

If I dont want the system to carry out availabilty check, I can switch off the indicator in requirment class or at schedule line category.

My question is why we have these indicators in 2 places.

It is written we can fine tune these settings at Define procedure for schedule line category settings

Could anyone explain in details with Business scenarious

Thanks in advance

Hi,

1. Availability check at Requirements Class level -

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.

2. Availability check at Schedule line category level -

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.

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

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

Note -

1. At the global requirements class level, the availability check can only be switched on in combination with the transfer of requirements. At schedule line level, the settings are proposed from the requirements class.

2. If the availability check is switched on at requirements class level, it can be switched off at schedule line level. However, you cannot switch on the availability check at schedule line level, if it is switched off at requirements class level. You can make this setting at schedule line level. But the system ignores it and the setting for the requirements class applies.

3. Also, at schedule line level when the availability check is switched on, the transfer of requirements can be switched off. For example, this makes sense for inquiries or sales information.

4. The settings specific to schedule lines for performing an availability check are only relevant for sales documents. In the shipping documents, the settings from the requirements class and the delivery item category are used. As with the schedule line category, the availability check can be switched off as required in the delivery item category.

In Requirement class, we can activate the Availability check only if TOR is active but TOR can be activated independent of Availability check. Hence if we want to activate only Availability check and not TOR (like in quotation), we can do it from Schedule line category fine tuning.

HI,

The requirement class is also used by PP/ SD Module, where as the schedule line parameters are used for SD purpose. It is the main reason why we can control the TOR and AVC at schedule line level.

One more important thing is if you uncheck the TOR and AVC at requirement level, then you cannot use TOR and AVC, for all the related documents. Where as if you uncheck it at schedule level, then only for those documents that have that particular schedule will not be having TOR and AVC.

In a nut shell, Requirement class is Universal, whereas schedule line is specific.
