# Formula too Long Error

##### Board Regular
I have a sheet that refrences cells in another workbook. Due to the long name of the other workbook, I am running into an Formula Too Long Error.

I see on Excel Help that formulas are limited to 1,024 characters.

Is there any kind of workaround for this other than renaming the file?

### Excel Facts

Return population for a City
If you have a list of cities in A2:A100, use Data, Geography. Then =A2.Population and copy down.

Hi,

perhaps you can shorten the formula itself ?
example: replace nested IFs by a VLOOKUP

or cut it into parts
example of cutting to several cells
=IF(AND(A1 = "yes",B1 = "no"), "OK", "not OK")
you could put
=AND(A1 = "yes",B1 = "no") in C1
and shorten the formula to
=IF(C1, "OK", "not OK")

else INDIRECT might be an option
example

kind regards,

Here is the formula that I am working with....sorta.

Code:
``SUMPRODUCT(--(LEFT(OrigDatCopy!G4:G352,5)="SAPMR"),--(OrigDatCopy!J4:J352="EXP"),--(RIGHT(OrigDatCopy!\$H\$4:\$H\$352,3)<>"INT"),((OrigDatCopy!P2>TODAY())*(OrigDatCopy!P4:P352))+((OrigDatCopy!V2>TODAY())*(OrigDatCopy!V4:V352))+((OrigDatCopy!AB2>TODAY())*(OrigDatCopy!AB4:AB352))+((OrigDatCopy!AH2>TODAY())*(OrigDatCopy!AH4:AH352))+((OrigDatCopy!AN2>TODAY())*(OrigDatCopy!AN4:AN352))+((OrigDatCopy!AT2>TODAY())*(OrigDatCopy!AT4:AT352))+((OrigDatCopy!AZ2>TODAY())*(OrigDatCopy!AZ4:AZ352))+((OrigDatCopy!BF2>TODAY())*(OrigDatCopy!BF4:BF352))+((OrigDatCopy!BL2>TODAY())*(OrigDatCopy!BL4:BL352))+((OrigDatCopy!BR2>TODAY())*(OrigDatCopy!BR4:BR352))+((OrigDatCopy!BX2>TODAY())*(OrigDatCopy!BX4:BX352))+((OrigDatCopy!CD2>TODAY())*(OrigDatCopy!CD4:CD352))+((OrigDatCopy!CJ2>TODAY())*(OrigDatCopy!CJ4:CJ352)))``

This formula is what I am using to solve a problem I posted about here
http://www.mrexcel.com/board2/viewtopic.php?t=238803&highlight=

This is actualy slightly different than the one I am working on now, but it is basicly the same. The difference is it is refering to a sheet in a workbook called: FY07 Corporate IT Project Summary August Baseline (version 1).xls] so that workbook title needs to be added before each cell reference. I also need to add another critera for it to sort by.

Does this make any sense?

Do you have any suggestions for the original problem that dose not require such a long formula?

cut it into parts
other suggestions
shorten the sheetname
put formula in original workbook and refer to that cell

INDIRECT looks too complicated to me in this case

have you considered using named ranges? Simplifies reading the formula as well as shortening its overall length.

This is not aimed directly at solving your problem (though it would shorten the formula marginally), but rather at making formulas more efficient.

I note that you have used the TODAY() function many times in this formula. This function is 'volatile' and its repeated use in a sheet can slow the calculation of the sheet noticeably. A suggestion is to put the formula =TODAY() in an unused (and possibly hidden) cell (say IV1) and then refer to that cell in your formulas. So your formula would start off like this:
=SUMPRODUCT(--(LEFT(OrigDatCopy!G4:G352,5)="SAPMR"),--(OrigDatCopy!J4:J352="EXP"),--(RIGHT(OrigDatCopy!\$H\$4:\$H\$352,3)<>"INT"),((OrigDatCopy!P2>IV1)*(OrigDatCopy!P4:P352))+((OrigDatCopy!V2>IV1)*(OrigDatCopy!V4:V352))+((OrigDatCopy!AB2>IV1)*...
