You can refresh the
columns in a data source in the designer at any time. Be aware that
refreshing a data source means that all live report objects that are
connected to that data source will have their queries re-run.
Note: Refreshing a data source
adds any new columns that have been added to the table metadata. The
default formats and names of existing columns will be updated the
next time you open the report.
To refresh a data source
for a report, on the
Data tab, select the
data source, and then click
. When you refresh a data source for a report, columns
that have been deleted from the table metadata will automatically
be removed if they do not impact any objects in the report. If deleted
columns do impact objects in the report, then the
Repair
Report window is displayed so that you can repair the
objects that are impacted by the deleted columns.
For more information,
see Repairing Reports.
