CK44和CKR1的區別

執行CK44，會刪除如下數據：
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.
執行CKR1，會刪除如下數據：
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.
也就是說，CK44只是能刪除costing
run的一些管理數據，包括篩選和結構展開，即CK40N的前兩個步驟可使用CK44刪除；對於costing run的結果（mark、realease）是沒法刪除的，如果要刪除，必須用CKR1，即CK40N的後三個步驟需要CKR1刪除。
