CO--关于KOMKAKE和KOMPAKE结构的字段创建的说明

KOMKAKE和KOMPAKE结构是和经营范围（Operating Concern）的获利能力分析（CO-PA）的激活相关。

在SAP未配置和激活经营范围的获利能力分析时，这两个结构都只含有一个哑元字段（KDUMMY_KE），如下图：

当用户配置和激活自己经营范围时（TCODE:KEA0/KEA5），sap系统就会根据用户设置的特性（Characteristic）扩展这两个结构，其中特性来自VBKD，VBAK，PAPARTNER，KNB1，KNVV和KNA1的字段会添加到KOMKAKE中，其他添加到KOMPAKE中。

注意：

扩展到这两个结构的字段SAP系统是不会删除，也就是说只增不减。SD的顾问得注意这些字段在定价的字段选择里就可能会使用，在以前一个项目中CO的顾问激活了一个无用的CO-pA的模板，也就添加了一些无用的字段，sd顾问恰恰用了这个字段，导致定价的条件表无法传输到TST和PRD机器，引起许多的麻烦。

扩展后的结构参加下图示例：
