Some QRTs are open list and need to be handled in XBRL in a specific way. In the business table there might be 10 columns, 6 may be reported and the remaining 4 form the context of the remaining 6.
You can view the List QRTs and the data that forms the table key (non reportable descriptors) here
Some business tables / List QRTs are linked through a forien key, for example S.06.02 has two tables that form a TemplateVariant
- S.06.02.01.01 has 4 elements to the key: Asset ID, Asset ID Type, Matching Portfolio Number, Fund Number
- S.06.02.01.02 has 1 element in the key: Asset ID, Asset ID Type
Every element in S.06.02.01.01 with the same asset ID will share the same information on that asset that is held in both list QRTs.
