The SAP error message CNV_20200_CHECK019 indicates that there is an issue related to the FIFO (First In, First Out) valuation method in the context of the valuation level being set to the company code. This error typically arises during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.
Cause: FIFO Valuation Active: The error suggests that FIFO valuation is active in the system. This means that the system is configured to use FIFO for inventory valuation. Valuation Level: The valuation level is set to the company code, which means that inventory valuation is done at the company code level rather than at the plant level. This can lead to inconsistencies if the data being migrated does not align with this configuration.
Solution: To resolve this error, you can take the following steps: Check Configuration: Go to the configuration settings in SAP and verify the valuation method for the relevant materials.
