Instead of using a array formula, you could use the `COUNTIF()`

function to check for duplicates. Assuming this sample data:

You can add a flag in Column `C`

indicating duplicates in Col. `A`

using this formula in `C2`

, and copying it down:

`=(COUNTIF($A$2:$A$13, A2)>1)`

This results in:

Now, you can add a second "flag column", combining the boolean value of col `C`

with a check for `B>0`

:

`=AND(C2,B2>0)`

Now, we have:

Of course, you could combine both formulae - the result (again for `row 2`

) may look like:

`=AND((COUNTIF($A$2:$A$13,A2)>1),B2>0)`

As result, you have an additional column with a `TRUE`

flag for all rows that are duplicates and have an `amount > 0`

. Now, you can apply an `AutoFilter`

(Menu "`Date`

" -> "`Filter`

" -> "`AutoFilter`

") and filter for rows with that `TRUE`

flag:

*(tested with LO Calc - should work the same way using OOo Calc).*

`=AND(COUNTIF(A:A,A1)>1,B1>0)`

. Then, filter the sheet to only show rows where that column's value is TRUE. – Iszi Jul 29 at 21:26
