Filteringįilters are provided to the list binding as described in Filtering. For more information, see the API Reference in the Demo Kit. Use the grandTotalAtBottomOnly or subtotalsAtBottomOnly property with values true orįalse, respectively, or simply omit it. Property, you can request subtotals and a grand total individually.įor aggregatable properties where grand total or subtotal values are requested, you can globally choose where these should be Note how an $orderby option can address groups across all levels. Group levels can only be combined with filtering before the aggregation Group levels can be combined with the system query option $count : true for more information, see Binding Collection Inline Count. To achieve this, specify the names of the group levels in the The groupable and aggregatable properties. You can provide group levels to determine a hierarchy of expandable group levels in addition to the leaf nodes determined by In this case, an extra row appearsĪt the beginning of the flat list of contexts that contains the grand total values, as well as empty values for all other In addition, you can request grand total values for aggregatable properties. The list binding then still provides a flat list of contexts ("rows"), but with additional aggregated properties An appropriate system query option $apply is derivedįrom those. You can provide properties for grouping and aggregation. As an implementation detail, the annotation is only available if the corresponding node is expanded. As an implementation detail, the annotation might simply be missing for – An integer value which determines the count of the direct children of a group True means yes, false means no, undefined means that (the state is – A boolean which determines whether this node is currently expanded.Which corresponds to the grand total row, "1" are the top-level group nodes, etc. Like is usually helpful, because automatic type determination is not – A non-negative integer which describes the node level "0" is the single root node The following client-side instance annotations can be used to access a node level or expansion state. Normally, there is also a structural property of the same name as the custom aggregate, providing type information, etc. For SQL-based services, this might be implemented as follows:ĬASE WHEN min(Unit) = max(Unit) THEN min(Unit) END ThatĬustom aggregate must return the single value of a unit in case there is only one, or null otherwise ("multi-unit Additional property requests for anĮntity that already has been requested (see Data Reuse) as well as updating ofĭata including execution of bound actions and side effects are only supported for a recursive hierarchy.įor every aggregatable property, you can provide the name of the custom aggregate for a corresponding currency or unit of measure. Support the creation, deletion, or refreshing of data. For more information, see the vGroupĭata aggregation or a recursive hierarchy do not Data aggregation or a recursive hierarchy cannot be combined with grouping via a list binding’s first sorter.
