### Evaluation Time functions

These are the reporting specific functions BeforeReadingRecords, WhileReadingRecords, WhilePrintingRecords and EvaluateAfter. You can use these functions to guide Seagate Crystal Reports as to when your formula should be evaluated.

Should the formula be evaluated before retrieving the records from the database, while reading the records from the database but before the records have been grouped, sorted and summarized, or while printing the report, when the records are grouped, sorted and summarized? In general, Seagate Crystal Reports sets an appropriate evaluation time for your formula, based on how much information the formula needs. For example, if a formula uses a database field, then it cannot be evaluated before the records are read from the database. However, you sometimes need to force a later evaluation time than normal to get the desired effect. See Global variables for an example.
