Missing Parts List (Availability Check: Overview) (SAP Library

Missing Parts List (Availability Check: Overview)

The missing parts list displays the header data for the check and the results per component.

Results per Component

The components checked are categorized into three groups:

available components

missing parts

components for which an error occurred in the availability check

In the missing parts list, the system only displays the missing parts and components for which an error occurred in the availability check.

The components are displayed according to a color code depending on the situation. You can check the significance of the colors by selecting View ® Color legend. If you do not only want to see the missing parts and components for which an error occurred in the check but you require the complete list, select View ® Check result ® All components.

A number of fields (which you can change as necessary) are displayed per component, for example, material number, material short text, plant, storage location, requirements quantity, committed quantity and so on. You can change the selection of the fields to be displayed, that is, you can add or remove fields and you can also reorganize the sequence of the display.

The most important fields for the availability check are listed below:

requirements quantity

This is the dependent requirements quantity resulting from the explosion of the BOM.

requirements date

The requirements date is the date on which the components have to be available - this is usually the order start date of the planned order.

committed quantity

The committed quantity is the maximum quantity available on the requirements date according to the check of all components. It depends on the component with the smallest available quantity on the requirements date.

On saving the result of the check, this quantity is copied to the planned order as the committed quantity.

committed date

This date is the earliest date on which - per component - the total requirement quantity is available. If a component is never fully available, the system enters 99.99.9999.

ATP quantity

The ATP quantity is the receipt quantity of component available on the requirements date. This quantity may be greater than the committed quantity as it is often the case that some components are completely available on the requirements date but others are only partially available.

Header Data for the Availability Check

In the header of the availability overview, the system displays the following general data:

number of components included in the check

number of missing parts

total committed date (only calculated in the check according to ATP logic)

This is the date on which the complete requirement quantity is available including the in-house production time of the header material. This date is copied to the planned order as the order committed date on saving the results of the availability check. The total committed date depends on the following:

If the quantity required can be completely confirmed for the requirement date, the total committed date corresponds to the order finish date of the planned order.
If the quantity required cannot be completely confirmed for the requirement date, as not every component can be available in sufficient quantity by this date, then the total committed date corresponds to the date of the last material to be completely available plus the in-house production time of the header material.
If one of the components is not available in sufficient quantity by the requirement date and if this component cannot be made completely available for any later date, then the system cannot calculate a total committed date.

partial committed date/quantity (only calculated in the check according to ATP logic)

The partial committed date is displayed along with the partial confirmation quantity when the components are not completely available by the requirement date, however, a partial quantity is available on a later date (before the total committed date). Thus, this partial committed date represents the next point in time when a partial delivery can be made. Dates and quantities are based on the component with the least partial available quantity.

Further Functions in the Missing Parts List

Availability check per component

For information purposes, you can check the detailed date proposals per component. To do this, select the appropriate component and then select, Edit ® Check availability. Depending on the type of check carried out (ATP logic or check against planned independent requirements), you receive the following data:

Check according to ATP logic

The system displays the dialog box entitled, Date Proposals with the individual committed dates and quantities.

In the dialog box, you can also check the scope of the availability check, that is, you can check which stocks, receipts and issues are to be included in the check.

Moreover, from this dialog box, you can branch to the period totals display (pushbutton, Period totals) and to the availability overview of the components (pushbutton, ATP display).

In the availability overview, the system displays the checked dependent requirements as simulative dependent requirements (SimReq) as they are not yet saved in the database.

Check against planned independent requirements

The system displays the total requirements.

Here, the system displays the planned independent requirements as well as the dependent requirements that were assigned (that is, consumed) for the components selected. As the dependent requirements are not yet saved in the database, they are displayed as simulative dependent requirements (SimReq).

Selection of Other Fields for the Missing Parts List

To change the selection of the fields, select View ® Choose fields.

The system displays the dialog box entitled Chosen Fields: Sequence.

To add new fields to the display, select the pushbutton entitled Selection list...

The system displays the dialog box entitled Selection List displaying all the fields available where you can select the appropriate fields.

To save the new selections, select Copy and close.

Deleting Fields in the Missing Parts List

To delete fields, select View ® Choose fields.

The system displays the dialog box entitled Chosen Fields: Sequence.

To select the fields you want to delete, double-click on these fields.

The selected fields are then flagged to be deleted.

Now, press the pushbutton entitled, Delete.

The highlighted fields are deleted from the list.

To confirm the deletion, select the field entitled, Copy.

The fields deleted here are no longer displayed in the availability overview.
