Is there a list of available string function that can be used in custom expressions. I am specifically looking for one to get a word count of a string separated by a delimiter (a ; in my case). we have a multi value reference attribute and would like to enforce there are atleast 2 values in it.

Functions Reference for FIM 2010 There is no build-in function for this. You will have to write your own custom expression for this. Cheers, Markus Markus Vilcinskas, Knowledge Engineer, Microsoft Corporation
