    Posted: 06 Oct 2015 at 8:45am
Hello everyone,
 
  I am brand new to Crystal Reports. I am using 2008 and am stuck on an alert I am trying to create. I want the alert to look at 2 database fields and show me the records that do not match. Each field will have a Y or an N. They need to be the same. So if they are not I want the alert to show me those. Is there a match funcaiton or something similar that I can't find? I have looked through the help and on here, but didn't find what I was looking for.
 
Thanks for any assistance.

I am not sure you want an alert for this but rather a resulting report. Alerts are a 'pop up' message to 'alert' the user to something specific about that report, not really a feature for showing a resulting set of report rows.

  Well I have this report that is used for various reasons and by different people. It also has the information in it that I am creating this alert off of. So I figured when running this report it would alert me if these two feilds ever do not match when I run this report. Then I can choose to view the records. This will give me the list that I need to correct through the systems frontend.
 
  It currently has 2 other alerts that save the user from having to do mulitple groups to narrow down what they want. When they open the report, they click on those records if they want to narrow down the information as per the alert's conditions or just view the report as a whole if they choose.

so you are referencing using the 'view records' button in alert the pop up?
just use the formula
NOT(table.field1 = table.field2)

Thanks that worked. I actually ended up making a seperate report just for this data. Then I created an alert with (table.field1) <> (table.field2). I also got rid of my nulls. I read on here someone was having an issue with that so I am not sure if that helped or not.

unless you tell it how to handle NULL values it will exclude the result so
NULL <> 'Y' would be exclude from the evaluation results.
As a rule of thumb, when creating a formula there is a drop down choice on how to handle null values. Set it to 'use default values for nulls' and it eliminates the above exclusionary issue.
