Stop the tp process on the system (kill -9), but apparently it was always restarted. All the same I deleted the request from the queue and re-added it but I still got the little truck.
In the meanwhile however I also created a customer message at the SAP Service Marketplace and I got the following reply:
Kindly perform the following steps to resolve the issue:
1. Ensure that tp.exe process is not running at the OS level before proceeding with next steps.
2. STMS -> Import queue -> remove the requests with the status “RUNNING” (Truck Icon) manually.
3. STMS -> Import Monitor -> remove the obsolete entries “RUNNING” or error messages ( Select the entry, right click -> Delete option )
4. Ensure that there exists no clogged entries in TRBAT & TRJOB table entries. If exists remove them ( Ensure that tp is not running )
5. Run the TCode SE16 –> Enter the table name “TPSTAT” –> In the second field “TRKORR” enter the transport request number “D01K900481” –>Execute.
You will find an entry of transport request #*<SID>9xxxxx* in the table TPSTAT and now you need to delete transport request entry from this table as you can’t edit this table from R/3 level you need to delete this directly from the database level.
6. After deleting the transport request from TPSTAT table add the requests to the import queue and re-import them.
