## Questions and Answers about Microsoft 365

What is the purpose of the row context in DAX?

Answer: "Row Context is utilized when crafting a formula within a calculated column. Within this setting, the row context encompasses values from all columns of the current row. Should there be a relationship with another table, it also includes pertinent values from the related table’s rows."

How does DAX handle both filter and row context in a single formula?

Answer: "DAX manages both filter and row contexts by initially evaluating using the filter context, then applying the row context to pertinent rows. In essence, it amalgamates both contexts into a single streamlined context to simplify computation."

What is the primary function of the filter context in the context of DAX?

Answer: "The filter context acts as the predetermined set of filters that apply to the data model before a DAX expression is evaluated. Employing a measure in a pivot table, for instance, yields varying outcomes across cells as the expression is assessed against varied data subsets."

What is the context transition in DAX?

Answer: "Context transition in DAX involves the conversion of row contexts into their equivalent filter contexts, which is executed by functions like CALCULATE and CALCULATETABLE. Grasping this concept is crucial for advancing in DAX after mastering the row and filter contexts."
