This error indicates that there is a mismatch or inconsistency in the valuation level settings for materials in the system.
Cause: The error is primarily caused by the following reasons: Valuation Level Configuration: The valuation level in the material master data is set to "Plant," but the system is expecting a different valuation level (e.g., "Company Code"). This can happen if the configuration settings in the system do not align with the data being migrated. Data Inconsistency: The data being imported or converted may not conform to the expected structure or settings in the target system, leading to conflicts in how materials are valued. Missing or Incorrect Master Data: If the material master data does not have the necessary information for the plant valuation
