- vcLocalisationCode
- vcObjectSecurityLoaded
- vcTableType

N if no SharedSet_Id and Company_ID in main table
- vcUserLogin
Current User login ID
- vcUserName

- vcValidationExceptionList

- vhBuffer

- vhCacher

- vhFcComponent
field of t_FC_active_components.
Also a normal data item used for all direct calls from business to business components.

That way, each Loadstate of any component can use the same instance of the persistence component.
- vhFcStateDataSet
This is the handle to the dynamic dataset that holds all temp-tables defined in the business class making up the state of this business class.
You can add your own temp-table to this dataset to enable you to persist the contents of that temp-table, using the add-buffer() method on vhFcStateDataSet in method DefineState.
- vhFcSuper
Handle to the component at the top of the inheritance tree (the server component), as it is used to run iStartComponent.
- vhField

- vlDraftsActive
- vlDraftsActiveCache
- vlEnablePersistentCache
- vlEventPublishingActive
Flag indicates if event publishing is active.
If not, skip all time consuming queries on event publishing.
- vlEventPublishingActiveCache
- vlEventPublishingNeeded
- vlEventsPublished
This data item will be set to true as soon as one event is published from AdditionalUpdates (and so an instance of class BEventDaemonqueu is open and must be closed).

- vlFcOk
Logical data item for general use.
- vlFcQueryRecordsAvailable

This is true when :
