Choose Enter . A message appears specifying that you must check the validity of the object when changing the period type. You can ignore this message when creating the period type.

Choose  Characteristics New entries .

Enter the required data.

Note: The product allocation object must always be the first characteristic.

If product allocation should be carried out for the product substitution or in location determination within a rules-based availability check, then you should have included the characteristics from the enhanced field catalog (via product allocations : search help field catalog enhancement ) in the product allocation group.

Example:

If product allocation should be carried out in location determination, the field RULE_WERKS should be used instead of WERKS in the product allocation group. In the case of product allocation for product substitution, you should have included the field RULE_MATNR instead of MATNR in the product allocation group; otherwise, product allocation is carried out for the requested product .

Choose  Consumption period New entries .

Choose the product allocation group and define the consumption period.

If you have set the Without past periods indicator, the product allocation quantities from past periods are not used.
