Example: Report/Report Interface.Assigning reports
Before you can use the report/report interface, you first need to define a receiver report with variables for the information you want to pass on from the sender report. Next, define a sender report. Before leaving the report, you need to assign it to the receiver report. To do this, call up the function Extras
® Report assignment. The system will then display a dialog box in which you can enter the desired report. In another dialog box, you can enter a different application class to assign reports from that application to your sender report. Once you have done this, save your report.Calling up a report
You can call up a receiver report from any level of the drilldown list of your sender report. To do so, choose the function Call up report (in some applications called Other reports) and choose the report you want to execute.
You can return to any previously executed report from a receiver report using the function History.
Prerequisites for using the report/report interface
Variables
For the system to send information from one report to another, the receiver report must contain variables for the data you want it to receive from the sender report. These can be either local or global variables, and you can define them in the report itself or in the form used by that report.
In order for the system to be able to replace the variables with characteristic values via the report/report interface, it is important that you select the Enter when executing flag on the screen Enter variables.
For more information about variables, see the following:

Summarization levels (only CO-PA)
When you save a report after creating it, the system displays a dialog box with the title Read Summarization Data. As a default, the option here is set to Error message.
However, a receiver report usually only requires the system to read a small amount of data, since the information from the sender report limits the selection drastically. Consequently, it is not always necessary to use summarization levels. It is therefore recommended that you change the option to either Warning or No message.
Since a sender report can sometimes require a large amount of data, you should always use a report which uses a summarization level. In the dialog box Read Summarization Data, you should accept the default setting, Error message, to avoid potential abends.
You can change this setting at any time in Change report under the menu option Extras
® Summarization level.
If you work with summarization data instead of summarization levels, you receive the dialog box Store Summarization Data instead of Read Summarization Level. Here the following settings are recommended:
