How to fix this error?

The balances of event-based revenue recognition can be posted by
period-end closing if the necessary conditions are met. Typically a
suitable status is such a condition. Very often this is the status
'technically completed' or alternatively the phase 'finished'.
Public Cloud
The balances can be reported using the app "Display G/L Accounts Line
Items, Reporting View". The affected object such as the project
definition or the sales order is used as a filter criterion. The apps
"Execute Revenue Recognition, My Projects", "Execute Revenue
Recognition, Projects", or "Execute Revenue Recognition, Sales Orders"
can be used to perform period-end closing.
