Total Outstanding Export Sales by Week, Commodity, and Country

This is a query from the export sales data, aggregating total outstanding sales by week, commodity, and country. The query is necessary to avoid double counting in the weeks where the calendar week ending and marketing year ending do not align.本数据集基于出口销售数据查询构建，按周、商品及国家维度汇总未结销售总金额。该查询逻辑可规避日历周截止日与营销年度截止日无法对齐的周次内产生重复计数的问题。
