Availability Check: Organizational Levels
Features
The availability
is check ed at different levels depending on the issue element. If, for example, an issue only involves one plant, you can limit the stocks, receipts and issues to be included in the check to plant level. If, however, the issue refers to a batch or a storage location, then the storage location or batch stocks must also be taken into account.Availability Check at Plant Level
Example:
The ATP quantity calculation results in the following:
Requirement 1 amounting to 1200 pieces can be completely covered. Receipt 1, 500 pieces, is used up completely and the remaining 700 pieces are issued by plant stock, leaving the plant stock quantity at 300 pieces. The plant stock can provide an ATP quantity of 300 pieces for future requirements.
Availability Check at Storage Location Level
Example:
Plant stock (1000 pieces) is made up of the stock from storage location 1 (800 pieces) and the stock from storage location 2 (200 pieces). Requirement 2 in amounting to 500 pieces is to be withdrawn from storage
location 1. This storage location currently contains 800 pieces. However, requirement 2 cannot be completely confirmed at plant level as only 300 pieces are available. Therefore only 300 pieces are confirmed for requirement 2. If the system confirmed the full requirement quantity, the availability of the confirmed issue 1, for which the issue storage location has not been specified and which draws on plant stock, would be jeopardized as it would be short of 200 pieces.If the storage location is excluded from planning or if it is planned separately, then there is no longer the need for an additional check at plant level since stock from this storage location is not contained in plant stock.
If a storage location is excluded from planning or if it is planned separately, the check cannot be activated without a storage location (see
Availability Check at Batch Level
If only one batch is entered, the check is carried out on two levels, first against the batch and then against the plant stock.
If a batch and a storage location are entered, the check is carried out on four levels, first against the batch storage loc
ation, then against the batch, the storage location and the plant stock.Just as with the check on storage location level, the
organization level with the lowest ATP quantity determines the result of the check.Availability Check for Individual Customer Stocks and Project Stocks
Individual customer stocks and project stocks are maintained separately in the system and are not contained in plant stock. If an issue is made from individual customer stock or project stock, the availability
is checked only for this particular customer stock. A two-level check does not take place.
