DAX Calculate Table: How Argument One Takes an Expression and Argument Two Requires a Value
In DAX theory for table functions like `CALCULATE` and `CALCUATE`, the first argument is formally defined as a scalar or table expression that remains unevaluated during function entry, while subsequent arguments are strictly required to be pre-evaluated values. This mechanism dictates execution order where filter context modifications must occur prior to the evaluation of the primary expression. The concept relies on distinguishing between instruction sets (expressions) passed by reference versus concrete data instances (values), explaining why override filters provided as expressions require implicit conversion before being applied to the existing filter state.
