Report builder time phase

Anyone having a problem with a time phase report set up in report builder.
We are on 3.00.632 and have set up time phase report similar to the one in
vantage. Are problem with the one in vantage was it didn't show the part if
there was no activity to happen on the part. We like to look at classes and
see all the parts in those classes. We buy and make these parts and often
have a minimum requirement to fill but can combo run these parts to meet
those minimums. By looking at all the parts we can spread our inventory and
cost over all the parts instead of stocking up on only parts with an
absolute need at the time of running the reports. We have run into a problem
with the part detail table and is showing obsolete or deleted requirments.
Many of these parts are used in kits that we put together. We will use an
existing kit template to create a new kit and delete the materials going
into the kit that are different. Those materials being deleted are still
showing up in the part detail. Does anyone know how to get rid of these. In
some cases the jobs are even completed and closed and the detail is still
there. Any help would be appreciated.
Thanks in advance.
