HP Intelligent Management Center Standard Software Platform - Manual (Page 708)

• The lower-right box displays the names of mapped database fields. When
you map fields in the upper boxes, they appear in the lower boxes.
For each database field that you have changed, highlight the report field and
the database field in the upper sections and click Map. The field names move
from the upper boxes to the lower boxes.
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. You can click OK to close
the dialog box without remapping each field listed in the upper-left box.
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. In these cases, you can select a report field in
the lower boxes (the program then automatically selects the database field)
and click Unmap. The field names will move from the lower boxes to the
upper boxes.
Note:
Crystal Reports does not automatically refresh the report data when you
close the Map Fields dialog box. To refresh your data, click Refresh on the
Standard toolbar.
Remapping processes
If you make changes to the active database or universe fields that require
you to remap the corresponding report fields, you can display the Map Fields
dialog box by choosing any of these commands from the Database menu:
• Verify Database
• Verify on First Refresh
• Set Datasource Location
Note:
There is also a global option called Verify When Database Driver Upgraded
(set on Database tab of the Options dialog box) that can make the Map Fields
dialog box appear when you first refresh a report's data after updating its
database driver.
