Excel DAX-基于多个相关表格的计算'；过滤结果

嗨，我努力计算结果，但仍然是错误的，希望任何人都能给出建议。非常感谢

所需结果：在[Product table]中有一个计算列，根据[Warehouse table]和[inventory table]中的过滤器显示此产品是否有库存

过滤器逻辑：

=
IF (
    CALCULATE (
        COUNTROWS ( 'Inventory' ),
        FILTER (
            'Inventory',
            'Product'[IfOnline] = "Online " && RELATED ( 'Warehouse'[Region] ) = "BJ"
        )
    )
        > 0,
    "BJ has inventory",
    "BJ has no inventory"
)

根据[库存表]，查看“区域”BJ中是否存在该SKU的在线产品库存

• （区域信息来自[仓库表]）&（在线信息来自[产品表]

根据第一步的结果，在[Product table]中显示上一次过滤结果中未出现的SKU

我的代码：

=
IF (
    CALCULATE (
        COUNTROWS ( 'Inventory' ),
        FILTER (
            'Inventory',
            'Product'[IfOnline] = "Online " && RELATED ( 'Warehouse'[Region] ) = "BJ"
        )
    )
        > 0,
    "BJ has inventory",
    "BJ has no inventory"
)

表关系如下所示：

这应该可以：

[column] =
IF (
[IfOnline] = "Online"
    && CALCULATE (
        COUNTROWS('Inventory'),
        Warehouse[Region] = "BJ"
    )
        > 0,
"BJ has inventory",
"BJ has no inventory"
)

如果数量为0，则最好对数量列求和，而不是对行进行计数

[column] =
IF (
[IfOnline] = "Online"
    && CALCULATE (
        SUM('Inventory'[Qty]),
        Warehouse[Region] = "BJ"
    )
        > 0,
"BJ has inventory",
"BJ has no inventory"
)
