Got it! You’d need to add a ‘Date’ column for the end date. ie in this instance, I’m setting the Due Date to today and then pushing the due date by 3 weeks. This can be a collapsed/hidden column so that team doesn’t see/use it. Then with a workflow, you’ll set the timeline with a start of ‘today’ and an end date of the ‘Due Date’ from above.
From what i can work out this will only let me select the timeline for the item not the sub item. The timeline on my items are all already set i want to set the timelines for my sub items.
Also, i don’t know if this is just a glitch because my laptop is too slow, but the timeline is being set when my due date column first sets itself to today, before it pushes its date to three weeks. the sequence looks like this.
Sub item created
Due date set to today
Item timeline sets to today
Due date pushed forward three weeks.
So even if there is a way of setting the workflow to change the sub-item timeline i think the lag between due date being set to today and being pushed three weeks would mean it wouldn’t work for me.
I may just have to use a date column as deadline in my subitems
The image above is showing you’re able to adjust the timeline of the subitem. If the timing is an issue, I’d recommend adding a step with a delay of a minute or two.
