Systems.Core.ExtensibleDataObjects Entity

Namespace: Systems.Core

Extends data in other tables with attached files, custom properties, etc. Each row is an object, bound to exactly one row in the primary table. Each object can be bound to a row in a different primary table, specified in Entity_Type. Entity: Sys_Objects

Parameters

• customPropertyCode
  The code of the custom property
  Type: string

• search
  The search text - searches by value or description. Can contain wildcard character %.
  Type: string
  Optional: True
  Default Value: null

• exactMatch
  If true the search text should be equal to the property value
  Type: boolean
  Optional: True
  Default Value: False

• orderByDescription
  If true the result is ordered by Description instead of Value. Note that ordering is not always possible.
  Type: boolean
  Optional: True
  Default Value: False

CreateCopy

Duplicates the object and its child objects belonging to the same aggregate. The duplicated objects are not saved to the data source but remain in the same transaction as the original object.
Return Type: EntityObject
Declaring Type: EntityObject
Domain API Request: POST
