I have a column called "Metric ID" and I would like to create a calculated column that adds a 0 to each of the single digits like below so I can sort. This is SP 2007.

1.1.1.1 => 01.01.01.01
1.2.1.1 => 01.02.01.01
10.1.1.1 => 10.01.01.01
16.1.8.5 => 16.01.08.05
17.2.9.1 => 17.02.09.01
2.1.1.1 => 20.01.01.01
1.1.3.1 => 01.01.03.01
1.1.1.5 => 01.01.01.05

Hi,
in this way it will work:
1. Use the four calculated columns (from your other question / my suggested calculations)
2. Create a fifth calculated column, set it to return a number with three decimal places and use the following formula
=(1000000*FirstPart)+(1000*SecondPart)+ThirdPart+(0.001*LastPart)

Assuming that each part has a maximum of three digits.

Then the sorting will work:

Sorting by calculated number field
(Note: my initial field name is WBS instead of yours "Metric ID")

Rainer,

Thanks!  It worked but could you please break down the formulas.  I would like to understand your thinking.

=(1000000*FirstPart)+(1000*SecondPart)+ThirdPart+(0.001*LastPart)

Also, please explain this too.
Second part
=LEFT(RIGHT([Metric ID],(LEN([Metric ID])-(LEN(FirstPart)+1))),(SEARCH(".",RIGHT([Metric ID],(LEN([Metric ID])-(LEN(FirstPart)+1))),1)-1))

I just want to understand it all.

Thanks!

Hi,
as you mentioned, the sorting on the calculated columns is not working as expected and you can only choose two columns to be sorted on in the list view.

Therefore I convert the extracted parts into numbers and giving them the right "weight".
By multiplying the first part with one million and adding the second part multiplied with 1000, the third part with no "weight" and the last one with a division by 0,001 I will get a correctly formatted number

1.0.1.0 == 1000001.0
10.0.10.0 == 10000010
10.1.0.0 == 10001000

The second part calculation works like this:
Take the right part without the first part.
In this string search the next "." and take the left part of it.
