Diagnosis
Before the batch input folder &V1& can be deleted, the system searchedfor the associated background (batch) jobs. While doing so, it found ajob whose status was not yet set to "Complete".
When this folder is deleted, the folder may be deleted in dialog mode orin the background, AND the existing job may still be executed.
This could lead to multiple deletion of the folder, or to inconsistentprocessing of the folder.

System Response
Folder &V1& cannot be deleted.

Procedure
Analyze the relevant background job using transaction SM37:
Job name: ,,&V1&
User name: ,,&V2&
Planned start date: ,,&V3&
Planned start time: ,,&V4&
Check whether the job can still be run, and if so it does not need to bedeleted.
Otherwise delete the job and afterwards delete the folder again.
