如何解决计算循环小时数时发生CX_SY_ARITHMETIC_ERROR
我正在尝试找到一种方法来压缩来自sap cats表的数据。我只需要每个“ belnr”一个条目，而不是字段“ belnr”的多余条目。各个猫工时应添加到“ totalhours”的新字段中，并且还应该有一个新的“ counter”字段，该字段显示了总结了多少个相等的“ belnr”条目。 我有不同的解决方案，现在想比较运行时以获得最佳性能。进行一些测试，一切正常。但是，当我添加更多测试条目（大约在6000左右）时，我总是会收到异常“ CX_SY_ARITHMETIC_ERROR”。转换为“ 2995”时会发生。
下面，我向您展示声明部分和一个解决方案，因为所有不同的解决方案都需要大量阅读。希望你们能帮助我。我认为应该很容易解决，但是我无法解决...

解决方法
您的问题是结果表的totalhours类型。它的类型为catshours，实际上是一个长度为4的数量字段，因此它不能接受在itab lt_catsdb的大量记录中填充的总小时数。
这是检查此内容的简单测试：
" this var is equal to 12420.00 if p_enl = 600
DATA(sum_of_all_hours) = REDUCE dmbtr( INIT val TYPE dmbtr FOR wa IN lt_catsdb NEXT val = val + wa-catshours ).
" this is equal to 999.99
DATA(max_possible) = cl_abap_exceptional_values=>get_max_value( lv_totalhours ).
ASSIGN max_possible->* TO FIELD-SYMBOL(<max_possible>).
ASSERT sum_of_all_hours < <max_possible>. " <- this assertion will fail
在这里，我们检查可放入totalhours的{{1}}列的最大值，并发现它超过了其数据类型所允许的最大值，因此出现了错误。
解决方案：使用数量更多，长度更长的数量类型，例如BRGEW：
