filter过滤多个条件
我想按两个条件进行过滤。之后进行汇总。该咋写啊。求帮助。我下面的写法报强制从memberSet转化到string无效
total(currentMeasure within set filter([ids6].[heb_cxqb_01].[selling_channel_01],[ids6].[heb_cxqb_01].[selling_channel_01]='21'
and
[ids6].[heb_cxqb_01].[selling_shop_code]=''))
total(currentMeasure within set filter([ids6].[heb_cxqb_01].[selling_channel_01],[ids6].[heb_cxqb_01].[selling_channel_01]='21'
and
[ids6].[heb_cxqb_01].[selling_shop_code]=''))
