|Rule||In a table, if more than one Sbr:domainMemberItem is modeled under a single dimensionItem, these MUST be included using a dimensionRelationshipNode.|
|Explanation||Elements which are included in a definition linkbase must be included in a table using a dimensionRelationshipNode, except when there is only one active member for that axis. In that case a ruleNode may be used so this member can be modeled as merged in the table. Background to this rule is to ensure that not every individual cell is defined, just the axis (for example, through a d-link)|
|Is NTA rule||Yes|
|Is PE rule||No|
- 2018-03-01: Changed wording to begin with 'In a table...' to make clear the rule only applies to use of tables.
