Processing Available Objects
When an available object is changed through ER, these actions occur:
The object in the internal runtime structure is changed.
If the object is a form control or grid cell, row, or column, the screen is updated with the new value.
A BV form control shares the same value as the corresponding business view item. (Filter fields are an exception to this rule.) This means that:
FC data and BC data are always identical.
Whenever FC data is changed, BC items are changed to the same value.
Whenever BC values are changed, the FC runtime values also changes to the same values. This change may not immediately reflected to the screen.
On Control is Exited processing, the value entered into the form control is captured in both the BC and FC item for that control.
