Use
For each report that you create, you can assign a report layout. Via the report layout you define the layout features of the report, such as the page format of the report and the numeric format of the report data. When you use the Layout functions, you can set parameters for the report.
You received the SAP standard layout with your R/3 System. This standard layout is automatically assigned to each report you create. If you want to use the SAP standard layout, you can skip the following steps and go directly to
defining rows. When you first define a report, the default standard layout is always SAP. SAP appears in the Standard layout field at the top of each report layout dialog box.When you define a report layout, you can define a layout specifically for a report and you can change the standard layout assigned to a report.
Procedure

You can switch between the change mode of your report layout and the default parameters of the standard layout using the pushbutton Use standard layout or Define report layout. To change a parameter so that the standard layout value is not used in a report, you type over the current value. The value is not changed in the standard layout; it is only changed for that specific report.

Changes that you make to the report layout parameter values do not affect the standard layout values that are stored in the system. The report parameter values that you enter only affect the specific report that you are working on.
You can change standard layouts for reports; however, any changes you make affect other users' reports. For more information, see
standard layouts.For more information on the standard layout screens or for information about changing the standard layout, see
creating a standard layout.For information on how to change the standard layout assigned to a report, see
changing a standard layout.The system determines which format group to use based on the format group defined in the sets that are used in the report definition. Some report parameters can be defined using six variants of the parameter. These variants correspond to the format groups 0 through 5. Depending on the value entered in the format group field for a set, the Report Writer selects one of the six values. For more information on format groups, see
setting format groups in sets.
