Description
The Create entity selection command builds and returns a new, alterable entity selection related to the dataclass matching the given dsTable, according to the current selection of this table.
If the current selection is sorted, an ordered entity selection is created (the order of the current selection is kept). If the current selection is unsorted, an unordered entity selection is created.
If the dsTable is not exposed in ds, an error is returned. This command cannot be used with a Remote datastore.
In the optional settings parameter, you can pass an object containing the following property:
| Property | Type | Description |
|---|---|---|
| context | Text | Label for the optimization context applied to the entity selection. |
Example
var $employees : cs.EmployeeSelection
ALL RECORDS([Employee])
$employees:=Create entity selection([Employee])
// The $employees entity selection now contains a set of reference
// on all entities related to the Employee dataclass
