I will reinforce the need to check the management chain set up in JPA to handle your PVR and to make sure it ends up in the right place. After 3 weeks of some sterling efforts by the deskie and PSF to sort things out, I had to be given a theoretical posting so that my bosses could get at it. I gather the manning phrase is "Position Bouncing".
I can also agree with other posts that by keeping all informed once I had made the decision the whole process was one of the smoothest admin type things I had done in my entire service career. In the current climate, timing can be everything.
