You use revisions to keep track of changes in your specifications. If the Domain Administrator has set the software to archive revisions, you can view, print, and compare previous revisions of specifications with the current versions.
You can manage spec revisions in the following ways:
Locally
managing revisions that belong to a currently open spec. When managing revisions locally, you open a spec and then open the Revisions dialog, where you can add, edit, or delete current spec revisions. In this dialog, when you first select a revision numbering method, several options are available to you, including preliminary revisions (designated by P0, P1, P2…). After you select one of the other revision methods, you can no longer return to the preliminary revision method and this option becomes disabled. When using SmartPlant Foundation revisions, the revision numbering methods are not available for selection. Only the last five revisions appear in the Revisions dialog or in the spec title block.
Globally
managing revisions that belong to any number of existing specs. You do not need to open the Specifications module to manage revisions globally, only the Global Revisions dialog. Also, if you want to view all revisions belonging to all existing specs, in the Specifications module, you need to select Actions > Manage Spec Revisions. If you want to print out revisions belonging to various specs, you can select Actions > Spec Revisions.
In the Specifications module, you cannot revise instrument specifications that you assigned to a Specification Binder package in the Document Binder module. Therefore, the software prevents you from adding new revisions to these specs, or delete these spec revisions.
