Function Module 原文:http://www.cnblogs.com/qiangsheng/archive/2008/02/18/1071827.html General-purpose function. Function modules are external subroutines written in ABAP. Developed in the Function Builder, they are managed in a central function librar
Function Library 原文:http://www.cnblogs.com/qiangsheng/archive/2008/02/14/1068642.html Central repository for all function modules in the R/3 System. The function library is part of the Function Builder. ----------------------分隔线上面是 SAP 标准文档中提供的说明分隔线下
Function Group 原文:http://www.cnblogs.com/qiangsheng/archive/2008/02/13/1067699.html Group of logically related function modules that share the same program context at runtime. A function group is the main program for the function modules it contains.
Function Builder 原文:http://www.cnblogs.com/qiangsheng/archive/2008/02/03/1063196.html Tool for creating and managing function modules. You use the Function Builder to create, change, test and document function modules. You can assign function modules
SAP 中strlen()只能计算字符串的个数,不能计算含有中文字符串的长度,如字符串“SAP大波霸”,strlen('SAP大波霸') = 6,其实真实长度为3+3*2 = 9.我们可以通过cl_abap_list_utilities=>dynamic_output_length来精确获取字符串长度,下面我写了一个截取字符串长度的函数,供参考: FUNCTION zotfm001. *"---------------------------------------------------

自定义 function 方法名或函数名(参数1,参数2,...) { 方法体: return返回值:(可不写) } function abc() { alert("123"); (x); } abc(); abc(abcdefg); 不加abc 属于没有调用,是什么也没有的,什么也不显示 当alert(x)的时候,然后abc(abcdefg),这时就会显示abcdefg说明传的参数它用到了 function jiafa(a, b) { return a+b; } var result
