In "The Complete DAX Calculated Measures Course 2026," what is the fundamental role of the `CALCULATE` function when modifying filter context, and how does it differ from implicit filter context propagation?
`CALCULATE`'s main purpose is to remove all existing filters, whereas implicit context propagation adds filters based on the visual's context.
`CALCULATE` is primarily used to aggregate data by applying row-level security, while implicit context propagation is for time-intelligence calculations.
`CALCULATE` explicitly defines and modifies the filter context for an expression, allowing for complex scenarios, whereas implicit propagation is automatic and less controllable.
`CALCULATE` is exclusively for creating new tables based on existing ones, and implicit context propagation is for summarizing measures.

According to "The Complete DAX Calculated Measures Course 2026," when dealing with many-to-one relationships in DAX, what is the most robust approach to ensuring correct measure calculations that respect the "many" side's context?
Always use `SUMX` to iterate over the "many" side table and apply aggregations within the `CALCULATE` function.
Employ `RELATEDTABLE` to explicitly bring the "many" side's context into the "one" side's context for calculations originating from the "one" side.
Leverage the implicit filter context propagation from the "one" side to the "many" side, as DAX handles this automatically.
Utilize `LOOKUPVALUE` to retrieve values from the "many" side and perform calculations on the "one" side.
Q3Domain Verified
"The Complete DAX Calculated Measures Course 2026" emphasizes the importance of handling blank values in measures. What is the most idiomatic and efficient DAX pattern for ensuring a measure returns 0 instead of BLANK when no data is found for a particular context?
`SUM(Sales[Amount]) + 0`
`IF(ISBLANK(SUM(Sales[Amount])), 0, SUM(Sales[Amount]))`
`COALESCE(SUM(Sales[Amount]), 0)`
`IFERROR(SUM(Sales[Amount]), 0)`
