 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).

Note Note

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.

End of the note.

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.
