 Consideration of Lot Sizes and Other Master Data

Use

Capacity leveling that you execute after an SNP heuristic run considers – like the heuristic run - the master data created for it. However, there are some special features, which are explained below.

Features

  • Capacity leveling takes into account lot size data that is defined in the master data, that is, it takes into account fixed lot sizes, maximum lot sizes, and minimum lot sizes. The system does not take period lot sizes or lot sizes from production process models (PPMs) or production data structures (PDS) into account.

    The capacity leveling method that you choose governs the way in which the system takes into account lot sizes. If you choose heuristic-based capacity leveling, the system uses the same rules as for the SNP heuristic when taking lot sizes into account; if you choose optimization-based capacity leveling, the system uses the same rules as for the SNP optimizer.

  • Capacity leveling takes into account the rounding value defined in the location product master. The system does not consider the SNP rounding profile.

  • Capacity leveling does not take into account the target days’ supply defined in the location product master.

  • Capacity leveling (like SNP in general) does not support local time zones for transportation resources (which means you can only use the UTC time zone).

  • Capacity leveling ignores the minimum available capacity of a resource.

  • The following details are specific to optimization-based capacity leveling:

    • The optimizer does not support transportation lanes that have different source locations but the same destination location.

    • The optimizer does not support cyclical transportation lanes.

    • PPM or PDS sequences, where the output products of one PPM or PDS are also used as the input products of another and only the last PPM or PDS of this sequence is run (with procurement indicator P ), are not valid if the resource that is to be leveled is being used in at least two of the PPMs or PDS involved .

    • PPMs or PDS, in which the output product is completed in an activity other than the last activity, are not valid (this applies to SNP optimization in general).
