2352383 S4TWL - Conversion to S/4HANA 1610 Material Ledger and Actual Costing
In SAP S/4HANA, the material ledger is mandatory. Therefore, migration of the material ledger is required in the following scenarios:
Migration from SAP ERP to SAP S/4HANA 1610 or higher
Migration from SAP Simple Finance to SAP S/4HANA 1610 or higher
You always need to migrate the material ledger, even if you were not using the material ledger in the source system.
The note 2354768 includes all steps to be considered
Before starting the conversion, please make sure to implement relevant SAP Notes that are mentioned in SAP Note 2345739.

Behaviour of new CKM3 with the new architecture (MALENA):
It replaces the former CKM3 view Price Determination Structure.
The former CKM3 Price History view is still available via transaction CKM3PH for all materials (independent of price determination control and active Actual Costing).
All other views formerly offered by CKM3/CKM3N are no longer available.
• No separate view for Cost Components, but integrated in main screen
• Flag for selection of cost components not relevant for material valuation, or only cost components relevant for material valuation; by default selection of inventory relevant cost component split
• Display of WIP Reduction for material; by default WIP Reduction is hidden; If WIP reduction is displayed, both WIP reduction and consumption of WIP for order are shown in opposite sign in different folder.
• Plan/Actual Comparison is removed in new CKM3
• Technically, data are retrieved from table MLDOC, MLDOCCCS and MLDOC_EXTRACT and MLDOCCCS_EXTRACT
If actual costing active in the plant, all materials (price determination 2 & 3) will be able to display 'price history view' and 'price determination structure':
- Data prior to 1610 migration: data is retrieved from old tables (CKMLPP, CKMLCR, MLCD…). It should be displayed via transaction CKM3OLD.
- Data after migration to 1610: data is retrieved from new tables (MLDOC, MLDOCCCS). It should be displayed via transaction CKM3.
If actual costing is not active in the plant, CKM3 will be redirected to CKM3PH and only 'price history view' is displayed. This data will be retrieved from the 'old tables'.
For the unmigrated data, you need to use the transaction CKM3OLD. The unmigrated data are the data that are older than last period of previous year. For migrated data, in CKM3 or CKM3N you can show only the summarization data and without the individual posting lines and without material ledger settlement line. To show the whole posting, you need to use the transaction CKM3OLD.
You may need to use both of the transaction CKM3 and CKM3OLD if you have mixed data in the same period created before and after the upgrade to S/HANA.
Remark: Data older than last period of previous year (related to the time of system conversion) cannot be displayed via transaction CKM3 because the 'old' data has not been converted to the MLDOC-tables. To show data older than last period of previous year you can use transaction CKM3OLD ('Material Price Analysis') or CKM3PHOLD ('Material Price History').
