Although the Always Recost Material checkbox is selected in the costing run in the selection flow step, the system transfers an existing cost estimate. Why does this occur?
A transfer occured for a cost estimate with the same key. In other words, there's already a cost estimate for the material in the same period with the same costing type, costing variant, and costing version. This problem generally occurs if you create multiple costing runs in teh same period. If you create cost estimates with different costing versions, then teh system will recost all the materials.
Why does the system display "incorrect" results in the detailed reports?
In several cases, the reports correctly display the data, which has been updated in the database. To verify this, you can use analysis report RKACSHOW. You execute this report with Transaction SE38. Use the object to be analyzed as a selection criterion. The system generates an overview of all tables relevant to cost accounting and their entries concerning the object for analysis. You can find more information on how to use this report in SAP Note 28145.
