Availability Check Against Planned Independent Requirements 

Use

In the check against planned independent requirements, the system only checks the dependent requirement quantities against the open planned independent requirements created for the components. Therefore, neither the ATP quantity nor the receipts or stocks are included in this availability check.

This type of availability check is most useful:

  • if assembly planning (in the standard system, planning strategy 70) or phantom assembly planning (in the standard system, planning strategy 59) is used to plan the components
  • if the availability situation is required at short notice and the results from this check are precise enough.

Prerequisites

  • Checking group

You have assigned a checking group to the materials to be checked in the material master (MRP 3 view, Availability check field). With this checking group, the check can be made against planned independent requirements.

These settings for the checking groups are made in Customizing for Sales/Distribution or Production control under Define checking group, in the field Relevancy of check against planned independent requirements.

The following options are available for setting the checking group:

    • No check against planned independent requirements

You cannot check against planned independent requirements. However, the material can still be included in the availability check according to ATP logic.

    • Always check the material against planned independent requirements

You can check against planned independent requirements. Simultaneously, the material can still be included in the availability check according to ATP logic.

    • Only check the material against planned independent requirements if the material is a phantom assembly

The system can only check against planned independent requirements when dealing with phantom assemblies (special procurement key, Phantom assembly). Simultaneously, the material can still be included in the availability check according to ATP logic.

In the availability check against planned independent requirements, the checking group does not control the scope of the check as it is only carried out against planned independent requirements.

  • Consumption mode/Consumption period

You must maintain the following indicators in the material master record to determine the period in which planned independent requirements are allowed to be consumed by dependent requirements.

    • Consumption mode, that is, the direction of the consumption. You can determine whether planned independent requirements can be consumed in the past and/or in the future.
    • Consumption period, that is, the length of the period (either in the past or in the future) during which planned independent requirements are allowed to be consumed.

Features

The system uses the open planned independent requirements quantity at component level to determine a confirmed quantity and this quantity is copied to the planned order header in the Confirmed quantity field. As opposed to the availability check according to ATP logic, however, the confirmed quantity is not recorded in the dependent requirements. The planned independent requirements of the components are not consumed by the confirmed quantity but by the complete dependent requirements quantity. In following availability checks, the system can confirm quantities only 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:

  • partial confirmation date
  • partial confirmation date/quantity

Activities

To check availability against planned independent requirements, select Edit → Components ATP in the header data screen of the planned order.
