USERELATIONSHIP DAX Function (Relationships management)
Specifies an existing relationship to be used in the evaluation of a DAX expression. The relationship is defined by naming, as arguments, the two columns that serve as endpoints.
Foreign (or primary) key of the relationship.
Primary (or foreign) key of the relationship.
The function returns no value; the function only enables the indicated relationship for the duration of the calculation.
USERELATIONSHIP can only be used in functions that take a filter predicate as an argument, for example: CALCULATE, CALCULATETABLE, CLOSINGBALANCEMONTH, CLOSINGBALANCEQUARTER, CLOSINGBALANCEYEAR, OPENINGBALANCEMONTH, OPENINGBALANCEQUARTER, OPENINGBALANCEYEAR, TOTALMTD, TOTALQTD and TOTALYTD functions.
USERELATIONSHIP uses existing relationships in the model, identifying relationships by their ending point columns.
In USERELATIONSHIP, the status of a relationship is not important; that is, whether the relationship is active or not does not affect the usage of the function. Even if the relationship is inactive, it will be used and overrides any other active relationships that might be present in the model but not mentioned in the function arguments.
An error is returned if any of the columns named as an argument is not part of a relationship or the arguments belong to different relationships.
If CALCULATE expressions are nested, and more than one CALCULATE expression contains a USERELATIONSHIP function, then the innermost USERELATIONSHIP is the one that prevails in case of a conflict or ambiguity.
