In Data Analysis Expressions (DAX), the `CALCULATE` function operates on a specific execution sequence where it first revises the filter context by evaluating all arguments beyond the sub-expression as independent override filters within their original contexts, rather than sequentially altering the environment for each step. These evaluated temporary tables are subsequently consolidated and applied simultaneously to establish a new, distinct filter state exclusively for executing the final argument (the measure or calculation). The function strictly adheres to a cleanup mechanism where it restores the global filter context to its initial state immediately after returning the result, ensuring isolation between calculations within an expression column.
