initial 是初始值得意思，就是判断变量是否为初始值，变量是不同的数据类型初始值也不一样，不一定是空，比如如果变量是日期类型，它初始值就有可能是‘00000000’.
initial 是初始值得意思,就是判断变量是否为初始值,变量是不同的数据类型初始值也不一样,不一定是空. 比如如果变量是日期类型,它初始值就有可能是 ‘00000000’. 改变日期类型为’0000’,满足space条件但是不满足is initial。会发生错误 所以在判断变量是否为初始值的时候应该用is initial SPACE 是什么 空白...

IS INITIAL:用于检查一个变量的值是否为其数据类型对应的初始值。 比如我定义一个引用变量但不对其赋值,则IS INITIAL判断一定为abap_true. IS ASSIGNED:对于检测的field symbol,该关键字判断该field symbol是否分配有内存区域。 这三个关键字交织在一起,就形成了一些有趣的排列组合。
