In the Engineering Part Revisions screen, it is allowed to selct multiple lines do the “Replace Old Revision” for multiple parts at once. 

The customer selects 2 lines as follows and proceed to check the “Replace Old Revision”. (It is allowed to select multiple lines and RMB) 

The “Replace” process starts using the wizard.

However, it only completes for one part rather than all selected parts. This is misleading as the customer is given the ability to select multiple parts to be Replaced.
