Thanks for all the suggestions.
Our development team reached out to me saying max(load_date_field_name) won't work and they are getting the following error when they manually enter the MAX function in the sql window.
Error: The server failed during a search operation.
Does SQL functions ( MAX, AVG etc., ) are supported in CMOD query restriction ?
Meanwhile the team reached out to IBM and they got back saying whenever a particular index value is selected we can only use the operators that are listed in the operator symbols pane and it doesn't show any sql functions.
