Page History
When objects are selected to be checked out they are automatically flagged to be checked out for Update. Use the Read only 
and Write (Update) options 
options in the toolbar to indicate how each object, or group of objects should be checked out. The Read-only column indicates the current setting for each object.
Objects can be removed from the check out dialog by using the delete option 
option in the toolbar.
Use the Cross References toolbar 
toolbar option to select associated objects to be checked out at the same time. For example if you review the references for a file you can select to check out all or some of the fields used in the file at the same time.
On the resulting Cross References dialog, the Master only 
toolbar option can be used to selected all cross reference objects which exist on the Master Repository but do not exist in the local Visual LANSA Repository.
