Change Documents for Material Classification data Changes

Dear Friends,

We have configured custom classification objects for material master and also we are able to maintain the material characteristics using MM01, MM02 and also using ALE interface. But I am not able to find the Change Documents in any of the table CDHDR & CDPOS. Please let me know what needs to be done to capture the change documents for a material classification changes in this case.

Many thanks for you inadvance.

Beast regards,

    Change logging of all Classification (including Material Classification) is controlled in the Class type configuration.

    SPRO -> Cross Application Components -> Classification System -> Classes -> Maintain Object types and Class types -> Select Object Table = MARA -> Double Click Class Types under MARA -> Select Class Type 001 and Display -> Check whether "Change Docs" check box is checked on.

    Also check that another flag "Chg. docs for Class" is set on all Objects under the Class type too (by double clicking the Objects folder for a Class type).

    If the Change docs flag is checked on for the relevant Class type and Object then change docs are logged in CDHDR and CDPOS tables for object "CLASSIFY"

    Also the "Change docs" flag cannot be set unless the "Multiple objects allowed" flag is also set in the Class type configuration.

    Please refer [SAP Note 65124 - Classification Change Documents|]

    Also the above note says and I quote: If "Multiple objects allowed" indicator is not set, start the RCCLUKA2 program. The classification data are converted and the indicator 'Multiple object types allowed' is set. Now you can set the indicator 'Change documents' in Customizing of the class type. However, it only says that change documents are generally possible for this class type. Therefore you have to select objects under 'OBJECTS' for which the change documents are to be written.

    So if the Class type doesn't have "Multiple objects allowed" set (along with Change docs flag not set), there is also a conversion that needs to be run using program RCCLUKA2.

    Also when you transport the configuration to a target system, the program RCCLUKA2 should be run again, refer [Note 379180 - Classification data disappeared| ]

    Check by using Object class CLASSIFY in CDHDR and CDPOS tables.
