The archiving object CO_ML_DAT archives the period data for the Actual Costing/Material Ledger component.

Period data is transaction data that is used in single-level or multilevel material price determination. Data for closed periods that is no longer needed for reporting purposes can be archived, which deletes the data from the database.

Period data consists of the following:

• Material ledger period records

• CKMLPP
• CKMLCR

• Period records for activity types

• CKMLLACR

• Quantity structure (actual/plan/target)

• CKMLMV003
• CKMLMV004

• Summarization records from documents

• MLCD

Before archiving, you should make the Customizing settings for the archiving object CO_ML_DAT. This can be done directly from the application menu Actual Costing/Material Ledger.
