Cost code listing in Budgets

SUGGESTED

Our products have a number of possible budgets for various components.  We have setup a schedule of the budgets and have a an excel schedule within our project files that was compiled so that it matched the list of budget headings for ease of entry.

What we have found recently is that the list of cost codes in the project budget tab, no longer agrees with our list.  Anybody know of any reason the budget headings may have changed order.  Cant see any logic into why they changed (value, alphabetical. last used).
