SAP标准成本估算删除

执行CK44，会删除如下数据：

If you _deletea costing run, the data for
Selection	is deleted
Structure explosion	is deleted
Cost estimate	is not deleted
Marking	is not deleted
Release	is not deleted

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。
