-
To launch the
DataSearch Source Filter Setup form, click
Filter on the
DataSearch Source Setup form.
Note: You cannot open this form directly.
-
In the
Property Name field,
specify the IDO property for which you want to set up the filter.
-
Specify the operator to use for the filter. If you select
IS NULL or
IS NOT NULL, the comparison field and value
need not be specified.
-
Select the comparison type:
-
Literal: The property value is compared to
the literal value that you specify in the last field on this row.
-
DataSearch Source Property: The property
value is compared to another property value from the DataSearch source.
This
can be useful when you want to use a comparison of two properties to control
what records are searched. For example, if you wanted to search only orders
that do not have the full number of items shipped, you could set up the
property comparison
QtyShipped < QtyOrdered. Or suppose
you wanted to search only orders that were not shipped on time, you could set
up the property comparison
ShipDate > DueDate.
-
In the last field on this row, specify the comparison value to be
used for the corresponding comparison type.
-
Optionally, if you use multiple filter clauses, to instruct the
system to treat the clause as Boolean OR comparisons rather than Boolean AND
comparisons with the previous clause, select
OR Instead of AND with Previous
Clause.
-
To add the filter clause to the list of clauses in the display
panel, click
Add.
The clause is added to the list, formatted with the proper
syntax.
-
Optionally, use Steps 2 through 7 to specify additional filter
clauses.
-
Optionally, to remove all filter clauses and start over, click
Remove.
Note: You cannot selectively remove individual filter clauses: If
you choose to remove one, you remove them all.
-
Click
OK.
For complex comparison logic, it might be necessary to add parentheses
around filter clauses, to make sure they are evaluated properly. To accomplish
this task, manually edit the data in the display list.
Note:
To get a better understanding of how filters can be used, look at the
vendor level DataSearch Sources provided as part of the application
installation.
