Product/part revision
Products/parts gets a new revision number because of changes in materials/parts within the structure. These changes can be:
Adding/deleting material/parts.
Replacing a material/part with new material/part.
Changing quantity at one or more materials/parts.
A purchased part is revised.
To be able to do such changes, a new version of the structure must be made, but several structure versions may have the same product revision number and drawing. The revision handling is different for parts and structures.
Common for all these changes are that such change can lead to a new product drawing, and changing the revision of a part could therefore lead to upload of new drawing. Product structures may be changed (new version) for adding/deleting/changing operations. This does not lead to a new product revision or drawing. The new version will inherit these values/references from the previous version.
The Revision and Drawing fields are located to the left in the Article (ART) window.

A part (Class = M/P) does not have any structure and the revision control for these will therefore only be handled manually. The user (responsible for the part) can both change the Revision contents and upload a new drawing, but there will be no automatic update of Revision because of a new drawing or vice versa.
There is an inspect icon for revision setting behind the Revision field at ART. Clicking on this gives a popup where earlier revisions and attached drawings will be shown. New revision can be set (not counting articles with structures) and new drawing can be uploaded in the popup.
