不同时间段销售产品的一对多关系

Question

我需要跟踪一个品牌（商店品牌）相对于所有其他品牌的表现。我相信这需要一对多的关系。我的数据集如下所示：

日期	类型	产品编号	销售额
01.2020	店铺品牌	2345	500
01.2020	品牌	1111	400
01.2020	品牌	2222	425
01.2020	品牌	3333	450
02.2020	品牌	1111	300
02.2020	品牌	2222	325
02.2020	品牌	3333	350
03.2020	商店品牌	2346	600

但我需要对其进行转换，使其看起来像这样：

年份	月份	商店品牌产品编号	品牌产品编号	商店品牌销售额	品牌销售
2020	1	2345	1111	500	400
2020	1	2345	2222	500	425
2020	1	2345	3333	500	450
2020	2	2345	1111	0	300
2020	2	2345	2222	0	325
2020	2	2345	3333	0	350
2020	3	2346	1112	600	0
2020	3	2346	2223	600	0
2020	3	2346	3332	600	0

我有一个映射 table 可以显示哪些品牌产品可以与商店品牌产品进行比较。看起来像这样：

商店品牌	品牌
2345	1111
2345	2222
2345	3333
2346	1112
2346	2223
2346	3332

对于数据集中的每个时间段，所有品牌产品都需要与商店品牌进行比较。如果在某个时期内没有销售商店品牌产品，则这些需要列为 0，或列为空单元格。反之亦然，如果某个时间段内只有店铺品牌销售，则可比品牌销售额需要列为0，或为空单元格。

我正在使用 Excel 365，所以如果可能的话，请只 post 我可以在 Excel 365 中实现的答案，因为我目前无法使用 Power BI Desktop。

如果有任何不清楚的地方或我需要添加其他信息，请告诉我。

谢谢！
