I’m trying to copy a number in a mirrored column to another column the first time a status changes to something.
For context, we have resource’s rates which I want to lock in while doing some costings. The problem I’m having is when I look back on this item in 6 months and the resource’s rate has now changed, it changes all the historical calculations and I can’t see what their rate was back then.
Here’s the formula I have now: IF({Final Cost Locked} = “Final Costs Entered”, {Subitems CPM Cost}, “Not Finalised”)
But of course the problem is that, so long as the status column “Final Cost Locked” = “Final Costs Entered”, it will keep updating the value to whatever the mirrored column currently displays.
I can’t for the life of me figure out how to accomplish this. Does anyone have an idea?
