Set up drill-through access in a source report
to link two reports containing related information. You can then access
related or more detailed information in one report (the target) by
selecting one or more data item values from another report (the source).
If you are using an SAP BW data source for the
target report and the target report contains a variable for a hierarchy
node, values from the source report can be values only of the data
item representing the leaf-level identifier of the hierarchy.
Before you begin
Before you begin, ensure that you have a report that will
serve as the source report and another report that will serve as the
target report.
Procedure
- In IBM® Cognos® Report Studio, open the target report.
- Create a parameter that will serve as the drill-through
column or that will filter the report.
For example,
to drill through or filter Product line, create the following parameter:
[Product
line]=?prodline_p?
Tip: Use the
operators in or in_range to enable
the target report to accept multiple values or a range of values.
- In the Usage box, specify what to
do when a value for the target parameter is not passed as part of
a drill through:
- To specify that users must select a value, click Required.
If
a value for the target parameter is not passed, users are prompted
to choose a value.
- To specify that users do not need to select a value, click Optional.
Users
are not prompted to choose a value and so the value is unfiltered.
- To specify not to use the parameter, click Disabled.
The
parameter is not used during the drill-through. It will also not be
used in the report for any other purposes.
Tip: If
the parameter is needed in the report for other reasons, then you
can also specify not to use it in the drill-through definition (Parameters table, Method, Do
not use parameter).
