On the
Crystal
Reports menu, click
Set Datasource
Location.
The Change Data Source dialog box
appears.
Select the new data source
and click
OK.
Another Change Data Source dialog box
appears.
Click the database field in
the new data source list.
Select the field you want to
map to the corresponding field in the existing data source list.
Repeat steps 3 and 4 until
you have mapped all the fields you want to map.
Click
OK.
You do not have to remap every report
field. For example, if you delete a database field, it is not necessary to
remap its corresponding report field, since you will not need that field in
your report.
On some occasions, you might want to unmap
or unlink report and database fields that you have already mapped. For example,
you might mistakenly map the wrong fields or want to map a report field to a
database field that you have already mapped.
