Use
If the system discovers that accounts or certain account assignment objects can not be posted to in accounting when it checks the
posting runs , it indicates errors in the posting run. Posting runs with errors can not be posted. If you can’t correct the errors via Customizing for accounting, you should reject the posting run. Afterward, you can again process all trips that the system included in this posting run in Travel Expenses dialog.Prerequisites
You can only reject a posting run if you didn’t create it as a simulation and the system was able to create trip transfer documents for it.
