Meaning of Availability check in diffirent screens and their connection.

[Former Member]

Hi,

There is a Availability Check field in Order Type, Material Master/Sales Gen/Plant, Schedule line Category and Delivery Item Category.

Could somebody help me by explaining what do they individually offer in terms of functionality and what is their connection with each other.

Thanks,

Rahul.

Hi Rahul,

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

OVZG, OVZ9 is maintained;

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.

Please also goto help.sap.com and search for documentation for ATP check. I think you could find basic customizing information on help portal.

Best regards,
