During the lifecycle of a plant, you will probably make changes to specifications for any number of reasons; for example, an instrument manufacturer may change some of the characteristics of an instrument, the process conditions may change, or you may just want to add a note explaining the conditions under which the instrument will operate. The revision feature is used to keep track of these changes.
You can view previous revisions for the specifications that were revised. Prior
to this, you must activate the revision archiving option in the Administration module.
For details, see Set Archiving Options for Report Comparison in the Administration Module help. With this option, you can save the specifications
with associated data to the database or to an external file.
