Instead of multiple filters in the Power BI Lookup Value function, you can create a single multi-column filter. This could optimize complex scenarios where the presence of Lookup Value in an iterator produces poor performance. This generally happens when the storage engine queries include CallbackDa...

Power BI can submit queries to the model using COUNTROWS in cases where it isn't explicitly requested by the user. For example, the filter dialog shows the count of rows for each value.Combined aggregation techniquesYou can combine the relationships and GroupBy columns techniques for aggregations....

WHERE a > 10 下列代碼段會為需要 LIMIT 子句的驅動程式提供 LimitClause 實作,其格式如下:[OFFSET <offset> ROWS] LIMIT <row_count> LimitClause = (skip, take) => let offset = if (skip > 0) then Text.Format("OFFSET #{0} ROWS", {skip}) else "", limit = if (take <> null) then...

Performance, performance, performance…We are always striving to achieve it (or at least we SHOULD strive), but there are so many things to keep in mind when tuning Power BI reports. The first step in…
