Hi Hector, That is an interesting challenge, so I did some experimenting. It is possible to add a combined column on the Assignment Report that shows the Planned Completion Date of the Issue or Task using this textmode: displayname=Planned Completion Date textmode=true valueexpression=IF(ISBLANK({opTask}.{plannedCompletionDate}),{task}.{plannedCompletionDate},{opTask}.{plannedCompletionDate}) valueformat=atDate Similarly, it is also possible to group by "whichever" Planned Completion Date (by Month, Year, in my example – that's the "=MY" part) using this grouping in textmode: textmode=true group.0.valueexpression=IF(ISBLANK({opTask}.{plannedCompletionDate}),{task}.{plannedCompletionDate},{opTask}.{plannedCompletionDate}) group.0.linkedname=task group.0.groupdatesby=MY group.0.notime=false group.0.valueformat=atDateAsMonthString In both cases, the trick is to check whether the Assignment has a blank Issue (aka OpTask) plannedCompletionDate, and if it is blank, use the Tasks, otherwise, use the Issue's. To double check, you can also add the Issue Planned Completion Date and Task Planned Completion Date to your report, too, which illustrates which one is driving. Regards, Doug
