When you set a version zone, all subordinate version zones are reset. You cannot
set any more version zones at subordinate nodes of the set version zone.
Nodes that indicate the beginning of a version zone are displayed in the tree view
by means of a white field with a "V" in the icon.
The version zone is defined via the PROCESSINGRANGEID field in the
DNCNODEINFO table.
Here, you can enter the NODEID of the node that defines the version zone.
This means that in the PROCESSINGRANGEID field, this node and all subordinate
nodes have the entry of the NODEID for the node with which the version zone is
formed.
Upload
The version zone is taken into account when an NC data file is uploaded. Before
an NC data file is uploaded, a check is carried out to determine whether the
maximum number of versions of this NC data has already been reached within this
version zone.
If this is the case, either an older version is deleted or the "Delete Version Dialog"
is activated (depending on the version strategy). Users can delete older versions in
this dialog.
