Indexed fields have some colored markers. A view is a collection of tables for simplifying data for end-users.
The only way to handle it is to avoid report on the tables which make the view. You can identify if the source of a field is a view or table with the help of a Database Expert, which lists them separately. In order to find which tables make the view is even trickier since you need the help of the database documentation. In addition, by using the Oracle database and turning off the casesensitive option, you can speed up reporting times. But you will have to rewrite the existing report. Excessive Use of Sub Reports Every subreport is another individual report accessing the database. Hence, it will run on every record of the main report loads if the subreport is in the detail section. Even if it is in the group section, the sub-report will run numerous times. Therefore report sections are the ideal place for sub-report since they will run only one time. But as far as performance is related, it will still run one crystal report as two. Hence, the best way is to cancel the performance issue is to simply not use them. Most of the subreports are not even necessary, and you can achieve the same results by using other methods through grouping or formulas. Using the wrong ODBC driver
