sap 隐式增强 系统升级后会覆盖么

Posted 2023-05-17

SAP有四代增强：
第一代： user exit（需要access key， 现在一般不用这种增强了）
第二代： customer exit
第三代： BADI
第四代： Framework（显式增强， 隐式增强）

个人认为BADI是最好用的， customer exit也会经常用到， 隐式增强功能很强大，需要一定的debug技巧。

其他增强还有BTE, validation, substitution这些可能FI模块用得比较多 参考技术A 一代增强升级会被覆盖，四代不会覆盖。

如何根据用户权限屏蔽或显示SAP的订单中的成本显示

程序目的说明:
1、 SAP标准程序不能在销售订单（va01 va02 va03）中根据权限显示或不显示有些订单定价过程的敏感数据。
2、 由于公司需要对销售订单定价过程的敏感数据（如成本数据）进行控制，因此需要增强系统功能，使系统能根据用户权限和定价敏感数据的设置来决定显示或不显示定价过程中的订单定价过程的敏感数据。
3、 修改了LV69AFZZ的userexit_field_modific_leer
userexit_field_modific_kzwi
userexit_field_modific_kopf
userexit_field_modification
