新建函数时要先建函数组，打开菜单Springen->FGruppenverwaltung->Gruppe anlegen新建函数组。
新建函数，输入名称F5新建。选择函数组，输入描述。
Attributes 基本属性（如果要用于外部调用 Processing Type选Remote-Enabled Module）
Import 输入参数(外部调用 Pass Value打钩)
Export 输入值(外部调用 Pass Value打钩)
Tables 输入输出的表
例：
Attributes： Processing Type选Remote-Enabled Module
Import： I_MATNR
Tables： 输出表E_MARA
Source Code
FUNCTION ZDTFTEST1.
SELECT *
INTO CORRESPONDING FIELDS OF TABLE E_MARA
FROM MARA
WHERE MATNR = I_MATNR.
ENDFUNCTION.
