USER'S GUIDE - ShipWeight

Click on the text ‘Click to create parameter’ in the table. The text will change
to ProjectID (name of the parameter).
Optionally, set ‘Allow multiple values’ to True in the options list. This will
enable the user to include several ProjectIDs in the selection. This could be
useful when creating a report to include data from a project and its masterproject.
Press OK to close the dialog box.
IMPORTANT: You can only add a dynamic list of ProjectID-values to a
parameter if you have installed Crystal Reports version XI. Users of earlier
versions of Crystal Reports must skip step 2, 3 and 4 above.
8.3.3 Create Record Selection Formula
Now we are ready to create the data filter. We want to create a filter that
selects only data with ProjecID equal to the current project name.
Filtering of data is done by creating a Record Selection formula. On the
Report menu, choose ‘Selection Formulas’ and then ‘Record…’ Now the
Formula Workshop opens.
In the Report Fields list, expand the database and the appropriate database
table, in this case the item table. Select the database field ProjectID with the
mouse, and drag it into the formula text window.
In the formula text window, type the sign of equality after {ITEM.ProjectID}.
