When you choose Verify Database from the
Crystal Reports menu, the program checks the active databases
and reports. If it detects changes, the report must be adapted to prevent
errors.
Crystal Reports automatically
adapts the report if it detects any of these changes:
Fields have been added to the
database.
Fields that are not used in the report
have been deleted from the database.
Field positions have changed in the
database.
Data types have changed for fields in
the database.
