matinal：SAP 如何删除标准成本估算

执行CK44，会删除如下数据：

The administrative data for the costing run (name, description, selection and structure explosion) is deleted. The material cost estimates themselves are not deleted. You have to _deletethem in a second step CKR1.

执行CKR1，会删除如下数据：

When you _deletea material cost estimate, the following data is deleted:     Basic costing data     Cost component split     Itemization     Log

In test run mode, a list appears showing the cost estimates that can be deleted.

In the reorganization mode, the system issues a message detailing the number of cost estimates deleted.

也就是说，CK44只是能删除costing run的一些管理数据，对于costing run的结果（mark、realease）是没法删除的，如果要删除，必须用CKR1。
