Aconstructor expressionwith the value operatorVALUEcreates a result of a data type specified usingtype. The following can be specified fortype: A non-generic data typedtype. Exceptions to this rule are: When an initial valueVALUE #( )is passed to a generically typed formal parameter, the type...
通过使用 WITH KEY 选项可将内表整行定义为其关键字,如下所示: ...WITH KEY = <value> ... 如果<value>的数据类型与表格行的数据类型不兼容,则将<value>转换为表格行的数据类型。 对于此类关键字,也可以选择由某个基本数据类型或内表直接定义的,而不是由字段串直接定义的特定内表行。 (3)将行首定义为...
6. Reduction operator REDUCE I. Definition ... REDUCE type( INIT result = start_value ... FOR for_exp1 FOR for_exp2 ... NEXT ... result = iterated_value ... ) II. Note While VALUE and NEW expressions can include FOR expressions, REDUCE must include at least one FOR expression. ...

being evaluated and assigned first, the current value is used in every assignment. If the entire structure or structure components from the left side are needed on the right side, however, they can be saved in local helper variables using aLETexpression, since this expression is evaluated first...
2.Table expression - Chainings ABAP的链式表达,可以帮助我们以更短精炼的代码做到内表数据的读写。 试想一个具有多层嵌套的内表,采用read table的方式那么代码可能看起来像这样。 Read table t_a into s_a with field1 = value1. If s_a is not initial. Read table s_a-t_b into s_b with field...

CHECK [NOT] expression [COMPARISON operator value]. ``` 其中,expression表示需要检查的表达式或变量;operator表示比较操作符,可以是等于、不等于、大于、小于、大于等于或小于等于;value表示需要比较的值。 例如,下面的代码片段检查一个数字变量是否大于100: ...
An element element can be specified directly or by using a path expression path_expr and must have one of the valid data types. In a multivalue path expression, it is sufficient for the condition to be true for just one of the values....
连接内表各行 concat_lines_of( [table =] t [sep = s] ) 将内表<t> 各行以为分隔符连接布尔运算 boolc( logical-expression) 如逻辑表达式为真,返回„X‟ 否则返回„ ‟ boolx( bit = i bool = logical-expression) 返回值为一个Byte, 如果逻辑表达式结果为真,则此Byte第i位置1,否则置0 ...
