SAP CO的若干表

COEP contains line items whereas COSP and COSS are summarized tables. So if COSP/COSS is contains sufficient information for your report take them, the performance should be much better as taking the figures from COEP.

译:coep包含详细的行项目，而cosp和coss则是汇总表。所以cosp/coss包含充足的信息用来制作成本报表，而且效果要好于直接从coep取数据
