Overview: Report/Report Interface
Use
The report/report interface lets you link together a number of smaller reports each containing a limited number of characteristics so that you can report on a number of different combinations of data online.
This helps you to avoid the problem of having particularly large reports, whose large volume of data often means that they cannot be constructed online and have to be planned as a background job.
Integration
Among other things, the report/report interface lets you
For an example of reports connected to other reports within an application class (costing-based Profitability Analysis), see the CO-PA example reports 0-SAP07 (sender report with the characteristics "Customer group" and "Product group") and 0-SAP08 and 0-SAP09 (receiver reports with the characteristics "Customer" and "Product").
Features
Exchange of data between reports
With the report/report interface, you can combine information from several reports. To do so, you need to define sender reports and receiver reports. The sender report sends data to the receiver reports using variables which you define either in the receiver reports or in the form they are based on. The sender report supplies values for these variables when you execute the receiver report.

Example: Report/Report Interface How to Use the Report/Report InterfaceSplitting reports
The function Split report offers you a simple alternative to the report/report interface for instances when you want to jump from one drilldown report to another. You can divide a "large" report -- which contains a large number of drilldown characteristics -- into two reports to make executing the report online more efficient. This also makes navigating between the report lists easier.
You can find this function under the menu option Information system
® Define report ® Split.Once you have made all the necessary entries and entered the name of the report, save your entries. Then execute the report and choose the drilldown characteristic which should go into the new report. Enter a name for the report which is created as a result of the split.
You can execute the report as soon as you have split the report. When you reach the lowest level of the first report, the system automatically calls up the second report using the report/report interface. You can navigate back and forth between the two reports as you wish.
It is also possible to split a report into more than two reports.
If you have only split the report once, the system automatically executes the new report when you click on the symbol for the report/report interface. If you have split the report more than once, you receive a dialog box where you can choose which report you want to see.
