大侠讲解一下function group ,它在SAP中是什么角色？

Answer 1

我的理解是，一些function的集合。就象我们在用delphi 或vb等工具开发时，喜欢把具有相类似 功能的函数都放在一个代码文件中一样。这样可以在不同的程序中重复调用。 你也可以把function group看成是一个类（但不是实际意义上的类）。

Answer 2

我说一下我的理解 不一定很正确 ?仅供参考 就是把一些 相关的FUNCTION 放在一起 ?形成一个 GROUP ? 如 ： ?与时间有关的F ? 用日期返回月的 ? ? ? ? ? ? ? ? ? ? ? ? ? 用日期返回星期的 ? 放回所在月的最后一天的 ? 可能在一个GROUP里 面 ? ? 字符串前面 加0 的 ? 和 ?去掉 前面的0 的 ?就在一个GROUP里面 ?好管理和查询

When you create a function module, you must assign it to a function group. The function group is the main program in which a function module is embedded. ? A function group is a program with type F, and is not executable. The entire function group is loaded in a program the first time that you call a function module that belongs to it. ? The system also triggers the LOAD-OF-PROGRAM event for the function group. ? The function group remains active in the background until the end of the calling program. It is therefore a suitable means of retaining data objects for the entire duration of a program. All of the function modules in a group can access the group's global data. ? The same applies to screens. If you want to call one screen from several different programs, you must create it in a function group. You then create the ABAP data objects with the same names as the screen fields in the function group. The screen and data transport can now be controlled using the function modules in the group. Examples: Function groups SPO1 to SPO6.
