Once an item is released and gets a cost value assigned to Actual cost, we can revise the item in Upchain but the cost value is locked if the item is in same division project. If the Development version of item is copied to another division's project, the cost value turns to Estimated and can be changed.
What we are asking for here is allow the users to change the cost in the original Project too, when the Released item is revised to a Development version.
