  Related Information:
  The SAP error message MLCCS400 is related to cost accounting in SAP. Cost accounting is used to track and analyze costs associated with materials, products, and production processes. The cost component split is a breakdown of a product's total cost into its individual components, such as material costs, labor costs, and overhead costs. The planned cost component split is based on the product's bill of materials and routing, while the actual cost component split is based on actual costs incurred during production. Inconsistencies between these two splits can indicate problems with costing accuracy or production efficiency.
