Determination of the Condition of Rotable Parts

The CMC must be able to determine the condition of each rotable component (such as serviceable, unserviceable and so on) to correctly schedule and prioritize orders/operations, and to separate "good" components that can be installed on a technical object from "bad" components that require maintenance or repair work, or even scrapping. The CMC supports different methods to determine this condition:

  • Classified batches

The default class AD_ROT001 for batches is provided in Customizing for the CMC Profile , along with the default characteristic AD_ROTZUSTD representing the condition of the components. However, it is possible to create customer-specific classes and characteristics. For more information about classes and characteristics, see Classification System (CA-CL) .

Note Note

If you define you own classes and characteristics to determine the condition of rotables, you cannot assign these in Customizing for the CMC Profile. Instead you must assign them in the current settings of your productive system. For more information, see Maintaining Customer-Specific Classes .

Current Settings for CMC should be used with caution. They allow users to change settings in a productive system that are normally only available in a Customizing client. If you want to use your own class and characteristics for the CMC, we recommend only expert users have authorization for this function.

End of the note.

  • Status-managed batches

This method does not require additional settings for the CMC. The system automatically considers batches in condition "unrestricted" as serviceable and batches in condition "restricted" as unserviceable. For more information about batches, see Batch Status Management .

  • Split valuation

You can use different valuation types to determine each condition of the rotable parts. You group valuation types for the same condition in Customizing for CMC Inventory Groups . For more information about valuation types, see Split Valuation in Inventory Management .

  • Storage locations

You can use different storage locations for the different conditions of the rotables. For example, you can have storage location(s) that only contain serviceable rotables and storage location(s) that only contain unserviceable rotables. For more information, see CMC Inventory Groups .

The CMC also considers the condition of rotables in the range of coverage (ROC) calculation:

  • Condition Type: Classified Batches or Status-Managed Batches

The CMC reads the stock movements from Information Structure S034 . Information structure S034 updates key figures relating to material movements at plant, storage location, material and batch levels.

  • Condition Type: Split Valuation or Storage Locations

The CMC reads stock movements from Information Structure S464 . Information Structure S464 updates all key figures relating to material movements for all types of stock, including special stock. Information Structure S464 has been set up as a copy of Information Structure S031, but also includes materials on FFF class level.
