IF sy-subrc EQ 0 AND NOT lv_string CS INITIAL. WRITE: 'String is not empty'. ELSE. WRITE: 'String is empty'. ENDIF. 在这个例子中,使用NOT操作符将INITIAL关键字与字段lv_string结合使用,表示判断lv_string字段是否为空。 总之,INITIAL是SAP ABAP中的一个关键字,用于表达变量或字段的初始值,并且可...
以下是`IS INITIAL`的一些用法: 1.检查单个变量是否为初始值: ```abap DATA lv_variable TYPE i. IF lv_variable IS INITIAL. "变量lv_variable是初始值 ELSE. "变量lv_variable不是初始值 ENDIF. ``` 2.检查结构体或表是否为初始值: ```abap DATA lt_table TYPE TABLE OF i WITH DEFAULT KEY. DATA...
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...
ABAP里的IS BOUND, IS NOT INITIAL和IS ASSIGNED这组关键字,如果平时不留心,很容易理解地似是而非。今天我们就来说一说它们的区别。 先把SAP帮助文档抄过来: IS BOUND It checks whether a reference variable contains a valid reference. A data reference variable that contains a stack reference, on the ...

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。
