Switch the display currency – Cost Control

Switch the display currencyCost ControlYou can read a whole set in another currency without changing anything in it.The **display currency** control in the toolbar re-reads the whole set in another currency. The rail says which one you are in — *Grand Totals in EUR*.It is a view, not an editNothing in the set changes. Cost items keep the currency they were booked in, the budget keeps its own, and switching back gives you exactly what you had.So it is safe to switch mid-conversation — to answer a co-producer's question in their currency, or to give a financier the figure in the one their agreement is written in.Where the rates come fromThe linked budget's currency settings. **Edit Currencies** in the toolbar opens them.That means a rate corrected in the budget moves every converted figure here at once. It also means the set and the budget can never disagree about a rate, because there is only one set of them.Cost items are normalisedCost items are held in the currency they were booked in and converted for display like everything else. An import brings in a file in one currency — the mapping requires it — so a set fed by several accounting systems can hold several currencies and still read as one total.What to check before quoting a figureTwo things, and both are read off the screen:- **the display currency** the rail names; - **whether a filter is on**, because the rail totals what is shown — see [filter and search a cost control set](/kb/article/filter-and-search-a-cost-control-set).A figure quoted from a filtered set in an unexpected currency is the classic way to alarm a financier over nothing.Markdown
