Example
This screenshot shows an example of a Purchase Order report (tdpur4401m000), for which a few report elements are exported to an Excel workbook:

A green box refers to a report layout.
The blue text contains the Excel Output - Column and Excel Output - Row for the exported report element. The Excel Output - Rows properties are decreased to avoid unnecessary empty lines, or increased to provide enough space for the barcode.
Note: You cannot mix up elements between report layouts. For example, you cannot
move a header layout element to a detail or any other layout.
