Hi, is there an easy way to change the part number field of a datbook and update components in an old schematic?
What would be an easy way to do so?
Which flow are you interested in as your questions appear to be a mixture of PADS specific and general. If you want answers to PADS question there are dedicated communities for them.

Changing the Part Number in Databook doesn't really help in this case, though of course you do need to have the Part Number in there.
Once you have the new part number in Databook make sure you have 'Enable annotation to selected component' selected in your DataBook configuration - Edit Configurattion - Properties - Selected Component Annotation Tab.
Now use Find - Find and Replace Text - Select Find and Advanced. Look in Components, Find Properties - Part Number and the Part Number you are interested in.
Perform the 'Find' and this should select all components with this part number. In Databook select the new Part Number and then select the Annotate Properties to selected component buttn in Databook (sixth button down on the right).
When using databook, this is not a difficult process. It takes some time, but it's not hard.
First back up your designs to keep an original set. It will probably take more than one attempt to get what you want the first time you try this.
Then copy the original Part Number property to a Part Number Old property using the script in https://support.mentor.com/en/knowledge-base/MG511904
Now do you have unique properties on your schematic components to compare to your databook settings, perhaps Manufacturer Part Number or even a combination of fields like symbol name, decal, and value.
Edit the configuration of your databooks settings, RMB, Configure, Edit Configuration. You should see a screen like this:
The load column is what databook uses for comparing the design to databook. The Annotate column are the properties added into the design. To add new part numbers, you need to uncheck the Part Number property in the load column, and check only those valid properties to ensure you have a unique, green light part, when doing a databook compare. Unlike the defaults we ship, not everything should be checked for every property. Only a few load properties should ever be checked. Save the configuration as a new .dbc file,
Now you want to use Databook or the new Search verify to update your design with the new part number. Some additional description on this is in help and at this link:
