More often, people inadvertently create a circular reference, forĮxample by having a SUM function which includes the cell the SUMĮxample: In cell A10, you write this function: =SUM(A1:A10) Need a circular reference, I advise you to try to keep the cells whichĪre included in the circle as close together as you can so they can be
Note that circular reference circles can span multiple worksheets andĮven multiple workbooks (try to avoid that like the plague!). Detecting such multiple circular chains is very The first circle isĪ-B-C-D-E-F-A (green arrows). In the example above, there are two circles. To complicate things, cells may be part of more than one circular Which uses the value of cell B3, which in turn uses the value of theįirst cell, C2, completing the circle. An example of such a singleĬell C2 uses the value of cell D3, which uses the value of cell C4, When all cells within a circle are not part of any other circle, we Value, being the date of the last time Excel recalculated. One way could be the use of the TODAY()įunction, in combination with the IF function:Īs soon as an entry is made in cell A1, the IF function's testĮvaluates to false, making the formula in cell B1 point to its own Suppose you want to keep track of when an entry was made in a certainĬell, without using VBA. Which only updates under certain circumstances. This is sometimes used when trying to have a value in a cell The simplest type of a circular reference is where a cell references Only case where it could be important knowing which subtypes there are. Them here under the deliberate circular references, assuming that is the There are some sub-types of circular references to discern.
Especially important: Devise a way to clearly indicate the Model, stating clearly what your intentions are and how the modelįunctions. If -and only if- you are convinced you really needĬircular references to solve your problem, meticulously document your Such plant, using a circular reference may be a good way to model your Plants often have such streams and if you want to calculate a model of Include models of a chemical facility where (part of) an input stream ofĪ process is a recycled output stream of the same process. To have a calculation model do iterative calculations. Some people deliberately create (sets of) circular reference chains There is a way to rewrite your calculations in such a way that noĬircular references are needed. The most important thing to decide up front is whether the model youĪre trying to calculate actually is of a circular nature. References to discern: Deliberate circular references Simplistically speaking there are only a few types of circular Working with Circular references in Excel
