I exported a project as an .XER file from Primavera P6 version 7 and imported to a computer in which I have Primavera P6 version 6. I exported the file as a version 6 file (so that it could be read on the other computer).
When I imported the file and opened it, I lost my relationships, so when I pressed F9, everything got screwed. Do you know what happened? What step I missed or what step I did wrong?
Thanks,
