这段代码是创建了一个名为"ads_ec_ec360_gmv_kpi_overview"的表，该表的结构包括了三个字段，分别是订单支付成功金额（pay_ord_amt_fy）、历史截至当日存量会员数（mbr_cnt_std）和成交金额完成度（kpi_gmv_rate_fy），其中成交金额完成度是通过订单支付金额除以3000万得到，并保留了四位小数。

这段代码还包括了一条INSERT语句，将符合条件的数据插入到表中，并将数据分区到了业务日期（ds）这个字段下。具体来说，该INSERT语句的SELECT部分是从两张已存在的表（dws_ec_trd_cate_commodity_gmv_kpi_fy和dws_ec_mbr_cnt_std）中查询数据，将它们的结果进行了聚合，并得到了订单支付成功金额和历史截至当日存量会员数的最大值。最后，将这两个值作为参数，计算得到了成交金额完成度，并将这三个字段的值插入到了新创建的表中。
