if you change a due date of a specific task, specific due date field in portfolio will be also updated to a due date of a specific task.
P.S.
The difference of one day will occur in case you change a due date just before day changing.
I think that’s a rare case.
But if you need a perfect, you can append another dummy field of date in a project and a portfolio, set a same date for them and subtract/add them in formula fields of 1 and 7.
I’ve tested it on my side. When I set it up for the first time, specific date on portfolio is correct but if I try to change my task due date - the portfolio date doesn’t change.
YES! I was needing something like this this week and was really struggling. Moving the value to the dummy field is genius!!! Thank you so much! We have been building out new Project templates and Portfolios for our work flow, and only being able to manage/see the project due date and not one of the ones from a task inside the project (The count down is actually better!) has been a huge stumbling block to get the visibility for my team leads we need at a glance! I knew there had to be a way. Thanks again!!
