The one-side join key cannot contain duplicate values at its intended grain. That targets enforce relationship lookup uniqueness, not model product-promotion many-to-many membership.

One-to-many identifies a unique lookup key filtering repeated related keys. It may suit model unique region to many stores, not model product-promotion many-to-many membership.

One-to-one cardinality requires uniqueness on each joining column. It is useful for join two uniquely keyed record sets, not for model product-promotion many-to-many membership.

Multiple active filter routes can create ambiguous or surprising evaluation contexts. It is useful for resolving ambiguous filter paths, not for controlled bridge-related filter propagation.

CROSSFILTER changes relationship filtering for that calculation without globally changing the model. That is meant for measure-specific relationship direction, not controlled bridge-related filter propagation.

One-way dimension-to-fact filters preserve predictable star-schema propagation. It would address avoid bidirectional filter ambiguity, not controlled bridge-related filter propagation.

The active date relationship supplies the default filter path for time-based measures. It would address default order-date analysis, not independent order and ship date slicers.

USERELATIONSHIP activates an existing inactive date path within the measure context. That targets alternate shipment-date measures, not independent order and ship date slicers.

A proper date dimension provides time categories even when facts have no records that day. It is useful for continuous calendar dates for analysis, not for independent order and ship date slicers.

A shared date dimension avoids numerous generated date tables. It is useful for eliminate redundant autogenerated calendars, not for chronological month sorting.

Complete dates underpin standard time-intelligence patterns and stable calendar filtering. Its scope is complete date-table time intelligence, not chronological month sorting.

Fiscal attributes represent business period definitions independently of the Gregorian year labels. That is meant for noncalendar fiscal reporting periods, not chronological month sorting.

Display-specific columns improve usability without changing source record identity. That targets concise category labels for reporting, not geographic semantic classification of coordinates.

Hiding presentation fields does not remove keys needed by model joins. It may suit simplify the report author field list, not geographic semantic classification of coordinates.

Identifiers are categories, not meaningful additive measures. It is useful for preventing summing product identifiers, not for geographic semantic classification of coordinates.

Sales events represent flows and can be summed over each ordinary dimension. It is useful for sum additive sales across dimensions, not for compare monthly budgets to atomic sales.

Distinct counts are nonadditive across overlapping date sets. That is meant for avoid double counting returning customers, not compare monthly budgets to atomic sales.

Stock snapshots represent state on dates, not independent daily flows to add. It would address avoid summing inventory snapshots over time, not compare monthly budgets to atomic sales.

Calculated columns materialize row-derived values for use as categories or slicers. It would address persist row-specific categorical attribute, not model-based derived dimension table.

Measures respond dynamically to slicer and visual filter context. That targets responsive aggregate KPI, not model-based derived dimension table.

Upstream transformations can prepare stable columns before DAX model processing. It is useful for transform stable attributes during ingestion, not for model-based derived dimension table.

Composite hierarchy levels distinguish identically named members under separate parents. It is useful for avoiding ambiguity in named products within hierarchy, not for preserving valid category ancestry.

Hierarchies define related drill levels in an ordered geographic path. Its scope is multilevel geographic drill navigation, not preserve valid category ancestry.

An explicit hierarchy provides a stable multilevel date drill path. That is meant for user-controlled temporal hierarchy navigation, not preserve valid category ancestry.

Identifier fields should not be arithmetically summed. That targets prevent meaningless ID arithmetic, not display ratio measures as percentages.

Custom sequence keys control labels independently of lexical ordering. It may suit correct fiscal period ordering, not display ratio measures as percentages.

Model formatting preserves numeric values while controlling report presentation. It is useful for consistent formatted currency amounts, not for display ratio measures as percentages.

CROSSFILTER can override the relationship direction for a single measure. It is useful for disable a relationship path for one calculation, not for resolving dual-date relationship ambiguity.

Two date tables provide independent filter contexts for two business date roles. That is meant for independent simultaneous date filtering, not resolve dual-date relationship ambiguity.

USERELATIONSHIP activates the specified inactive relationship inside the calculation. It would address count transactions by alternate delivery date, not resolve dual-date relationship ambiguity.

Explicit membership bridges capture many-to-many associations with defined keys. It would address segment membership modeling, not repair fact-to-fact repeated key join.

Bridges represent multiple associations while the measure controls distinct counting. That targets avoid duplicate product counts across tags, not repair fact-to-fact repeated key join.

Security membership bridges require carefully tested propagation paths. It is useful for many-to-many authorization membership, not for repair fact-to-fact repeated key join.
