You cannot output the report. You must first make a selection

What causes this issue?

You can access stored results with <ZH>Output report</>. No results
have yet been stored for this report.

System Response

Instead of <ZH>Output report</>, the SAP System automatically uses the
function <ZH>Choose report</>. You can output the report immediately
afterward.

How to fix this error?

Begin the selection report. You should activate the "Store results
permanently" parameter if you want to be able to reaccess the output
later without having to select the values again.
