Hi there everybody
would anyone be able to explain to me how I can remove a constraint on a Finish Date when a project has been copied with constraint dates attached.
The star appears next to the date indicating a constraint but there is no constraint shown under the status tab. I have tried various things to remove these constraints but to no avail. These constraints are giving me huge negative floats on certain activities.

thanx

France

    Thanks for your suggestions Donovan.
    I have checked all the things you have mentioned except for the baseline suggestion. I will try it and let you know.

    Another possibility:
    If you had relationships to activities in another schedule then the constraints may arise from dates held in the "External Dates" field which are not necessarily displaid in the Activities Details Tab.

    In a possible way for your solution..try the following which can help you to an extent..

    Choose Project, Activities, then select the activity whose constraint you want to define.Display Activity Details, then click the Status tab.In the Primary field, select a constraint type.Click in the Date field, then select the date to which the constraint applies.In the Secondary field, select a constraint type (if necessary).Click in the Date field, then select the date to which the constraint applies.

    The Secondary constraint list is filtered based on the value you select in the Primary constraint field.You cannot apply constraints to Level of Effort or WBS Summary activity types.

    Hi Mike
    Spot On!!
    You are a genius. I found the culprits in the "External Late Finish" column. I deleted these and ran the schedule. All the negative floats are gone.
    Thanks a lot for your help.

    regards
