availability check

Availability Check

Use
The availability check in Shop Floor Control checks whether the components, production resources/tool or capacities required for a production order are available.
Checking the Availability of Material

Use
Before you start production, you have the option of checking whether all the material components production resources and tools (PRTs) assigned to a production order are available on the calculated requirements dates.

Features
In a production order, the system can only check a material component, if it is
Kept in stock
Not a phantom item
Not a bulk material
Availability checks can be triggered either automatically or manually:
The availability of components in an order can be checked automatically during order creation and/or order release. You specify in Customizing(OPJK) per order type and plant whether the availability should be checked automatically. In addition, an automatic availability check can be carried out when the order is saved.
You can always trigger a manual availability check
The checking scope is defined via the Checking Group (in the material master) and the valid Checking Rule (in Customizing).
They define:
Which MRP elements are taken into account in the check
Which inventory categories are taken into account
Whether the replenishment lead time is taken into account
Whether the check is also to be carried out at storage location level
In Customizing (checking control) you specify which quantity is used to check the availability of a material. You can choose between the following:
Availability Check Against Planned Independent Requirements
In the check against planned independent requirements, the system only checks the open planned independent requirement quantities created for the components. This means that the ATP quantity is not included in this availability check nor are receipts or stocks.

This type of availability check is most useful:
if assembly planning or phantom assembly planning is used to plan the components
if quick statements about the availability situation are required and the results from this check are precise enough
The system uses the open planned independent requirements quantity at component level to determine a committed quantity and this quantity is copied to the planned order header in the Committed quantity field. As opposed to the availability check according to ATP logic, however, the committed quantity is not recorded in the dependent requirements. The planned independent requirements of the components are not consumed by the committed quantity but by the complete dependent requirements quantity. In availability checks that follow, the system can only commit quantities for the amount of planned independent requirements that have not yet been consumed.
In the availability check against planned independent requirements, the following dates/quantities are not calculated:
overall commitment date
partial commitment date/quantity
ATP quantity
In the check according to ATP logic, the system checks whether the dependent requirements of each component are covered by specific receipt and issue elements or by stock. This check is carried out dynamically, that is, each time you carry out the check, the system recalculates the current situation. If a quantity can be committed for the requirement date, the system enters precisely this quantity as the committed quantity in the dependent requirements and the ATP quantity for the components is reduced by the committed quantity. Therefore, in the next availability check, dependent requirements can only be committed for the amount of the remaining ATP quantity.

Checking Group
Every material that is to take part in the availability check must be assigned to a checking group. Assignment is carried out in the material master record.
Using the checking group you can define
Whether the materials to be checked are locked during the availability check
If the "Block with TrOfQties" indicator is set, the committed quantities are stored in a table of locks. This leads to more exact results because the check results of an order are already taken into account before saving when other orders are checked.
Whether the normal ATP quantity or the cumulated ATP quantity is used
The check with cumulated ATP quantity is recommended because in this check, inconsistencies in commitments, which can be caused by postponed receipts, are avoided.
The checking group is used to group materials that are to be checked according to the same criteria (see scope of check).
You can also switch the availability check off for a particular checking group. Materials with this checking group do not then take part in the check. This is useful, for example, if the materials are to be planned using KANBAN.
A checking group must also be entered in the material master record (MRP data screens/SD data screens) for assemblies or components that are to be checked against planning. The checking group is used to control whether the check against planning is permitted. You have the following options for setting up the checking group:

No check against planning
If the checking group is set up in this way, no check against planning can be carried out for this component in the production order. The material, however, can take part in the check according to ATP logic.

Always check the material against planning
If the checking group is set up in this way, a check against planning can be always be carried out for this component in the production order. At the same time, you can also execute a check according to ATP logic for this material.

Only check the material against planning if it is a phantom assembly
If the checking group is set up in this way, the check against planning can only be carried out for this component in the production order if it is a phantom assembly (special procurement key: phantom assembly). At the same time, you can also execute a check according to ATP logic for this material.
The settings for the checking groups are made in Customizing for Shop Floor Control (Operations ® Availability Check ® Define Checking Group) in the RelChkPlan field.

Checking Rule
You can maintain the following checking rules in Customizing:
Checking rule for created orders (availability transaction '1'):
This checking rule applies to
manual checks in a created order
automatic checks during order creation
automatic checks when a created order is saved
Checking rule for released orders (availability transaction ‘2’):
This checking rule applies to
manual checks in released or partially released orders
automatic checks during the release of an order
automatic checks when a released or partially released order is saved
The checking rule for backorder processing is defined per plant. It applies exclusively to availability checks carried out in backorder processing.
You define checking rules in Customizing for Shop Floor Control (Operations ® Availability Check ® Define Checking Rule). You maintain checking rules per order type in Checking Control (Customizing for Shop Floor Control, choose Operations ® Availability Check ® Define Checking Control).

How is the Availability Determined?
The availability is determined according to the ATP method (available to promise). Using this method, the system checks:
Whether the material requirements can be covered on the requirements date
At what point in time the requirements can be covered if full coverage of the requirements is not possible on the requirements date
Committing Partial Quantities in Availability Checks
As a rule, the system tries to commit the entire requirements quantity of a component, providing the ATP quantity is sufficient.
Committing the entire quantityOrder quantity: 100 pieces

300 pcs
200 pcs
Component B
100 pcs
40 pcs
40 pcs
Component C
50 pcs
200 pcs
50 pcs

If you want to ensure that the system only commits quantities that are needed in production, you can set up the commitment of partial quantities in Customizing (production scheduling profile).
In a partial commitment, only a percentage of the requirements quantity is committed. The committed quantity received by all components that are checked is determined by the component with the lowest relative committed quantity (commitment factor).

At What Level is the Availability Checked?
The availability check can be carried out at plant, or at storage location level. At which level the check is actually carried out depends on the data maintained in the material component and the checking scope: If a storage location is specified in the reservation, the check is carried out at storage location level, unless the checking scope specifies that the check should always be carried out at plant level.
If a check is carried out at storage location level and the components are available, the system automatically carries out an additional check at plant level. For performance reasons we recommend that you only carry out this type of check where required.
If, during an availability check, a material requirement exists with reference to a sales order / project, the check is carried out in the individual planning section of the sales order / project.
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.
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.
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.
You must activate an automatic check when the order is saved in Checking Control.

Carrying out an Availability Check
You can carry out an availability check either for the entire order, or for an individual material component in the order.
Checking all Material Components
To check the availability of material components for the entire order, choose Functions ® Availability check ® Material - ATP, or Material - planning.
The system carries out an availability check. If material components are not available on their requirements date, the system activates the status "material shortage" in the production order.
Checking Individual Components
You can carry out an individual check from the component overview, from the missing parts overview and from the missing parts list.
To check the availability of an individual material from the component overview, proceed as follows:
Choose .
The system branches to the overview screen of all the material components contained in the order.
Select the material component, whose availability you want to check. Choose Component ® Availability ® Check availability.
The system carries out an availability check. The system issues a message informing you whether or not the component is available on its requirement date.
For more information on how material availability is checked, see PP Production Planning / Material Requirements Planning.

Checking the Availability of Capacities
Use
When creating or changing a production order you can check capacity availability. The system checks for every operation in the production order whether there is sufficient capacity on the relevant date at the corresponding work center. The capacity requirements of other orders or operations at this work center are also taken into account.
When creating or changing a production order you can call up the capacity availability check by choosing Capacity. You can also call it up at operation level and at sequence level.
If you have called up the capacity availability check and there is insufficient remaining available capacity, a dialog box is displayed.
Choose Detail info to display detailed information on the capacity situation.
Choose Finite scheduling to carry out finite scheduling.
For more information, read Document PP Capacity Planning, Section View of Shop Floor Control (SFC)

Determining the Capacity Load
When determining the capacity load of a work center (basic load) in the context of the capacity availability check, the requirements of the operations with a particular status are taken into account. You specify which status is to be taken into account in Customizing for Capacity leveling in the selection profile via the requirements grouping. If you have not made any setting of your own, only released operations are taken into account.
