To all of you who answered, thank you. Unfortunately, i think i misexplained my problem.

I am a quite good user of spreadsheets, and i use cross-sheets formulas daily, with complex schemes. My problem is rather more complicated: scenario cells outside of the scenario's scope are blanks.

Try that:
- In a blank sheet (Sheet1), fill the 2 first cells (A1 and B1) with numbers, and the third one (C1) with its sum:
- Select only the third one (you can select a single cell with CTRL) and create a scenario out of it, let's name it "S1", and uncheck "Copy the whole sheet" and "prevent changes". - Now, in another sheet (Sheet2), reference the first sheet's third cell (the sum):
  it works, you see the sum on Sheet2.
- But instead, reference the scenario's same cell:
  you get a 0!
- Make a new scenario on Sheet1, but now selecting the 3 cells (A1:C1), and name it S2.
- On Sheet2, replace S1 by S2 in the formula: it works! You see the sum.

What happens is that the scenario doesn't "see" cells that are not in its scope. So, although S1 "sees" the formula in C1, they use A1 and B1, which are empty for this scenario, and you get a 0. For S2, A1 and B1 are in the scope, the sum works.

But in my case, it is not possible to select the whole sheet as a scenario, as 90% of the sheet is not the part of the scenario and changes only when the statistical scheme is adapted. It would be a lot easier to just make as many sheets as i have scenarios. But it brakes the purpose of reusability.

To conclude, I see two real solutions to my problem:
- A "pattern" sheet: you write a pattern sheet, in which some cells are "reserved for values". All the rest is the mechanism you want to reuse. Then you instance this pattern as many times as you want, leading to one new sheet by instance. In each instance, you can freely modify the "value areas", the rest of the sheet use them and you get your results for this parcticular case. - Scenarios could have an option "silent full copy": for each scenario, internally the whole sheet would exist, using scenario values. So refering to a cell that is outside the scenario scope, but by mentioning the scenario's name would use the original sheet's value instead, and compute formulas if there are. That's almosyt like using the option "Copy the whole sheet" of scenario creation, except that this option makes new sheets that become independant of the original one, and modifying a cell in the original sheet does not affect the copies.

I hope i made it clear enough, sorry if it is still strange :)

Best regards,

In fact, i thought of possible solution after i submitted this question. Is
there a way to link cells between sheets in a way that they are "virtually
the same"? Changing B4 in a sheet would change also B4 in other sheets where
B4 is linked.
If cell B4 is on Sheet1 and you wish to automatically update cell E7 on
Sheet3, enter in E7 on Sheet3 =Sheet1.B4. The syntax is =SheetName.Cell

Because my problem is not more complicated than that finally: "i have three
sheets almost identical except for the 4 first cells, how do i avoid
maintening the three ones when i need to change a cell that is the same in
all three sheets?"

Then i thought of some kind of link. But i don't know...

Thank you!

I wonder if Calc can help in my case:

I'm writing a financial forecast for my company. We sell 3 kinds of products.
But they all use the same scheme when it comes to computing fees and incomes.
So i made one (big) table with all the computation process and the comments
(it has to be shown to financers). The product variables are isolated at the
top of the sheet.

Then i used scenarii on my variables (there are only 4 variables to define a
product). It's fine: i can switch scenario and i see all the matching
forecasted results on the computation table.

But now, i want a new spreadsheet summarizing our activity: we sell the 3 kind
of products, so i make a table with three lines, one by product. Rows are for
years (5 in my forecast). And of course, i would like this table to be
dynamic, and change with whatever variable i change in scenarii or formula in
the forecast table. The problem is scenarii are not the answer, because they
are by definition volatile: when you switch scenarii, all the data,
everywhere, gets adapted. Even naming a scenario and using its name when
refering to a cell doesn't work, because cells out of the scenario's frame are
considered empty.

So, is there a way to mix the scenario behaviour with dynamic tables mixing
data from all scenarii?

I thought of generic formulas: i could make only one sheet with all
computation, then 3 other sheets with only the variable data of each of the 3
products, and use the first same sheet formula in the 3 next ones to get my
results (in place). Then a 5th sheet could easily summarize all that. The
first sheet would not have any result, since without the data of the 3 other
sheets, it's only formulas.

I hope i was clear. Not easy to explain that, but i'm sure you see my problem,
and maybe someone has another, magical, solution.

Of course i could copy 3 times the whole sheet (data + computation), but that
means much more maintenance, since i'm changing often details in the formulas
(i should do changes three times always). And what about same case but with
10+ products?

Thank you for reaching this line of text :)

Best regards,
