the cards are reflecting an inaccurate lead time/cycle time

[Claudio Ramírez]

How can I edit the start date & end date of a Jira card? I'm migrating my cards from a physical board, therefore the cards are reflecting an inaccurate lead time/cycle time, etc

Where are you storing these dates?

[Claudio Ramírez]

i´m ussing the "Change completion date" and "Change start date" from de Context fields in the  Kanban Default Issue Screen

[Nic Brough -Adaptavist-]

Ok, so those are custom fields that your people are filling in.  If they're inaccurate, you'll need to talk to the people putting them in.  If you want to correct them, click "edit" on the issue and amend them.

the date entered is correct, the problem is that the report does not consider it and occupies the date the card was created or passed to done instead.

Ok, so which report is looking wrong?

Cumulative Flow Diagram

[Nic Brough -Adaptavist-]

Um, the cumulative flow diagram is supposed to represent the flow of issue change.  So it looks at when the issues were created or updated.

It doesn't look at other dates because they're not what it is supposed to be reporting on.

My guess is that you've added those two date fields to try to record something that's part of a process, but you should really have mapped the process into Jira.  Why does your change process not have status (columns) that show the progress of the issue through the process?  So that when something starts going through a change, it moves columns, and when the change is complete, it moves again at that point?
