Case insensitive search - IP15.3.0.0

Hi,

I am trying to implement Case insensitive on couple of fields. And tried few options:

a) Tried making the 'CaseInsensitive' parameter in CFG and 'Use default  Sensitivity' changes. but it didn't work as expected. Not sure, if this is not supported in IP15.

b) Tried :

Go to S_CONTACT table and search for LAST_NAME column

Right Click on LAST_NAME column-->click Case Insensitive

Apply, Activate table and then compile the table

But, it didn't work either.

Question:

After performing 'Case Insensitive' step on columns, I see that there are couple of 'Case Insensitive' columns created. But, when I check in the backend..I dont see these columns even after apply/activate. Are they supposed to be showing up.
