When is the Availability Checked? (SAP Library

When is the Availability Checked?

To check the availability of components, you can either use an overall check or individual checks:

An overall check determines the availability of all components within an order/ collective order. It can be carried out automatically, or you can trigger it manually.

An individual check determines the availability of a single component. t can only be triggered manually.

Note

By branching into the production order information system, you can carry out an overall check for several orders at the same time (see Collective Availability Check)

You can specify in Customizing whether an availability check is to be carried out automatically. You can also specify when the checks are to be carried out. You can specify, for example, that the check is to be carried out automatically during order creation or order release. In addition, you can specify that the availability check is to take place when a created or released order is saved. You make these setting in Customizing for Shop Floor Control by choosing Operations ® Availability Check ® Define Checking Control.

If the check determines in an overall check that a material component is not available on the required date, the system activates the status "missing part" in the order header. An overall check or an individual check can also deactivate the status "Missing part", if the check determines that the required quantity of all component has since become available (according to ATP logic).

You can access details on the results of an availability check in the following places:

The availability log offers you

the result of the check (i.e. whether all components are available)
a list of the missing parts
a list of the reservations that could not be checked (for example due to incomplete data in the material master)

The log is not stored when you exit the order.

The missing parts overview offers you

a list of the missing parts
the ability to process the missing parts (for example by changing the requirements quantity or the issuing storage location)
the date on which all components are available

The missing parts overview always displays the results of the last availability check carried out in the order, regardless of whether you have since exited the order.

The missing parts list offers you

a list of the missing parts

a list of the reservations that could not be checked (for example due to incomplete data in the material master)

a list of all components checked , if you select the menu options View ® Check result ® All components
the date on which the other components are available

The missing parts list is not stored when you exit the order.

If an availability check is carried out when the order is released, the system writes the results of the availability check in the release log.

Note

If you make changes in an order, which could affect the availability of its components (for example date or quantity changes), this does not automatically trigger a new availability check. For up-to-date information on any missing parts in an order, you should restart the availability check manually after you have made the changes.

Caution

You must activate an automatic check when the order is saved in Checking Control.
