After you click on the "Create statement run" button, you will be redirected to the page below, the Statement Run page of the newly created statement run. You need to take two steps to trigger the actual creation of statements for all the selected contracts.
1. Click on the "Create statements" button in the second horizontal menu bar.
2. Click on the "Update calculations" button in the second horizontal menu bar.
Suppose you make any changes to the catalog. In that case, organizations, contracts, accounting groups, or report runs, please always make sure that you press the buttons "Re-create statements" and "Update calculations" in your statement run. Only then will the changes be implemented on the contract statements of the statement run. When a statement run is already closed, no changes can be made.
