Copying WBS / Activities

Hi,

My consultant asked me to make a “Time Impact Program” as we have a new MEP sub contractor whose time of completion is seven months and a lot of civil/architectural work is still left from our side. The extension is given to the MEP works and the finishing work that is following MEP only.  What I did to save time, I created a new program “Clause 14 TIP” and copied the WBS with activities of my existing (that I have already exported/saved on the other drive before maintaining the baseline) into “Clause 14.029” program. I got everything copied into my new program but the “Schedule % Complete” is showing 100% while it is 0% in the original program. I am using P6-V7.0 (stand alone). My questions are;

• Why is it so?
• How can I turn that percentage to “0”?
• Is there any way to copy all resources, units and activities to my time?

Thanx - Cheers
