Since it is generally considered to be best practice to use auto-numbering for CAD documents, we have set up the Object Initialization Rule on organization level to generate a document number for our designers. Windchill is presenting that newly generated number when a new CAD document is created in Creo, however a designer can override that and enter an alternative filename. At check-in, the number in Windchill is the same as the CAD document's filename.
We would like to have the same functionality in a Save As. The filenames can be modified, but numbers can apparently only follow the OIR that sets the number to be generated. The checkbox that shows the numbers to be generated automatically now cannot be unchecked. This requires the designers to perform a lot of manual renaming to get the number equal to the filename.
