& & does not contain any data pages.

What causes this issue?

No data records have been selected for this report. The list thus only
contains the title page and end page, provided these are defined.
This might be due to the following:
Data records have been selected that generate only lines with the
amount zero. The 'Hide zero rows' function is also active (-->
Layout).
No data records have been selected because the sets used in the report
contain incorrect values, or, when you started selection, a variable
was filled with a value for which no data base records were selected
(for example, incorrect fiscal year).
The user does not have authorization for displaying the selected data
records.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

In report output, you can use the selection log ('Extras' menu option)
to find out whether data records for the respective report have been
read.
Check the sets used, as well as the values of the variables. If your
report group contains other reports, you can display these using the
selection list.
