Available in: Logi Info Source code name: SubDataLayer

The SubDataLayer builds a hierarchical data layer. It allows the addition of child rows under the parent DataLayer. The child rows can be displayed with a SubDataTable placed under a DataTable. Parent/child relationships are established with one or more columns from each DataLayer that match, specified in SubDataLayerRelationColumn elements.

You can have any number of SubDataLayers under the parent.

NamePossible ValuesDescription
ID
UserDefined
(Required) The ID attribute is a pervasive attribute that uniquely identifies an element within a definition file. The ID needs to be a unique value within the definition.
OrphanRowExistence
True
False
With SubDataLayers, it is possible that some child rows will not have a matching parent row. These are orphans. Sometimes it is possible to prevent orphan rows by ensuring that the SubDataLayer doesn't return orphans. In this case, set Orphan Row Existence to "False", and the request may run faster. Otherwise, use the default value of "True" to prevent errors.
