My Desktop at wotk has just been upgraded to Windows 7 (Previously Window XP).  I now find that when I try and run Tops down estimationg. P6 freezes and I have to force myself off.

The messeage that comes up when I do this is that P6 is waiting for a response from the user, but the expected Tops down estimation options window does not open.

I would appear that there is a compatability issue with window 7 and the Tops down estimationg function in p6.

Does anyone know how to resolve this

HI Gents



If you talk about top down estimation in Cost, then you need to start with your CBS- Cost Break Down Structure. That usually align with the contract BOQ structure. Once you have the high level setup then you breakdown to the next detail level ..... until to the level that you are setasify or unable to break anymore. Then you have a top down estimation.



If you refer to plan Top down estimate then it is very similar but it start with WBS instead of CBS and break down the activity and establish linkage between activities. then you will have a top down estimated schedule



Good Luck



Alex
