Thank you. Actually, I have multiple projects and I would like to create a look-ahead report, so I need to show the data date for each activity.
I know that in the project view we are able to provide Data date column, but I was not able to add data date column to the Activity view.
I wished that there is a work around in Report view, Export file, or in P6 activity view itself.
For one project (baselined or not), a data date remains common for all the activities, ie, there is only one data date for allt he activities in a project. Therefore, if you must display it in any of your reports, you can display it as one of the header / footer options.
From what I understand, you have multiple projects open at the same time and you want Data Date displayed as a column, right ?
You can add a UDF and use global change or import/export with excel to store the data data for the individual projects. When you open the projects together you can stick the UDF column in and there you go.
I don't think there's a direct way of doing it in P6.
