I need to check last edited date as part of rule criteria on a custom field.
I need the workflow rule to check when the field was last populated - if it was updated (with text) more than 6 months ago a checkbox will need to be selected automatically. I'm ok with the last bit - I just don't know what criteria/ options to select for the first bit - does SF record when the field was populated?
EDIT: Added the following rule:
AND(NOT( ISBLANK( general_note__c ) ),ISCHANGED( general_note__c ))
but still cant work out how to add the 6 months criteria to it...
