In order to calculate the inventory requirements for each entry in the sales leads feed, the production manager needs to create a master detail data structure. 为了计算销售机会提要中每个条目的库存需求,生产经理需要创建一个主细(masterdetail)数据结构。
A sample entry from the master detail Input is displayed on the left-side tree, while the right-side tree defines the Output template of the transformation. 左侧的树中将显示来自主细Input的示例条目,而右侧的树则定义转换的Output模板。
A Transform operator is dragged from the operator's palette, and the output of the ForEach ( master detail ) operator is plugged into it. 从操作符面板中拖出Transform操作符,将ForEach(主细)操作符的输出插入到它里面。
Repetitive master detail requests are performed for large reports 为大型报表执行重复的主细节(MD)请求
In these cases, Report Studio report authors can use master / detail relationships as an alternative. 在这种情况下,ReportStudio报告作者可以使用主/明细关系作为一种替代方法。
