Once the document revision has been released, you'll notice that much of the data that you could previously modify is now locked. In particular, the information that gives the document its unique identity (the owner, document type, number, and revision) is now permanently established.
A specific document revision is released only once, and can be a used until canceled. A released document can appear on any number of non-implementing change forms (such as a change proposal or stop ship) as necessary.
If any product families have been specified for the document, then some attributes can be modified by members of the product team even after the document has been released. Your administrator designates who is a product team member in the Product families collection. If you want to modify the "product team attributes" of a released document revision, you must explicitly unlock it by selecting Unlock Object from the Edit menu.
If the released document's essential identifying elements (such as owner, type, or number) must be changed or the document has significant changes that affects its application or purpose, then you should create an entirely new document. The easiest method is to open the current document, then select the command Snapshot Duplicate from the Edit menu, and make your modifications to the newly-created copy.
If the modifications are less significant, such as making minor changes to the document attributes, structure or source, or attaching an updated file to the Files tab's Revision list, then you should create a new revision of that document.
For details, see the Revising a released document topic.
Finally, if you discover a clerical error that requires a minor "off the books" correction, your administrator can edit certain fields specified by the Administrator override rule.
