Cheating Pro/PDM: Set revision to a lower revision

For example, an object may currently be at revision 01.0 and you want to change it to 00.0.  PDM will not normally allow you to set to a previous revision directly.  There are 2 main methods which I can recommend:
 

Simple method

1. Use Design > Modify > Set revision to set the object's major revision to the last one available (which is defined by your pdm_major_rev.txt ), e.g. 99.
2. Then Set revision again.  You will be given a warning that there are no more major revisions available, and you are then able to enter the major revision of your choice, e.g. 00.  (Thanks to Olaf Corten and Ron Liston for this method).

Advanced method

1. Take a copy of the pdm_major_rev.txt from your client software installation and store it somewhere else so you can get it back later.
2. Edit the pdm_major_rev.txt on your client software installation.  Move the current revision entry (e.g. 01) to the end of the list.
3. Start up a new session of Pro/PDM client.
4. Use Design > Modify > Set revision.  You will be given a warning that there are no more major revisions available, and you are then able to enter the major revision of your choice, e.g. 00.
5. Close this session of Pro/PDM and restore your original pdm_major_rev.txt from step 1.
