The resultset of a query to external data source has exceeded the maximum allowed size of '1000000'

Was using this measure to calculate revenue amount in a specified reporting currenty by looking up an exchange rate table 

with the method outlined in this link


NetAmount Sum Ex = sumx(vwFactRevenueReportingEOM,
LOOKUPVALUE(vwDimExchangeRate[ExchangeRate], vwDimExchangeRate[DateID], vwFactRevenueReportingEOM[ExchangeDateID], vwDimExchangeRate[SourceCurrencyID],
vwFactRevenueReportingEOM[CurrencyID], vwDimExchangeRate[ReportingCurrencyID], values(DimReportCurrency[CurrencyID]))

, 1)


The measure works well in SSAS tabular model. But when I tried to use it in Power BI (direct query mode), it throws out the error of The resultset of a query to external data source has exceeded the maximum allowed size of '1000000'. 

The vwFact table and the exchange rate table have more than 1 million rows. But I have set filters to the report so that only a dozen records will be returning. 


Anyone got similar issues? I tested and the issue is with the Lookupvalue function used. Is there any workarounds EG not using the lookupvalue function?
