Wastebasket Service - Preventing Folder Deletion
Upon analyzing the log viewer you will see an error exception noting 'com.sapportals.wcm.command.DeleteResourceToWastebasketCommand' which references the wastebasket service.
This exception highlights and issue with the WasteBasket Service itself.
Occasionally this exception might also show that the associated folder + document is "locked" by a user even if the folder itself is empty.
What is the Wastebasket Service?
Activated by default in a standard setup.
Provides users with a means of fail-safe deletion i.e. users can be moved (deleted) to the wastebasket and restored/recovered from this point of call if required.
The wastebasket service is not running on the system.
If you navigate to the component monitor by choosing System Administration -> Monitoring -> Knowledge Management -> Component Monitor what do you see?
If you are presented with an exception highlight such as #com.sapportals.wcm.command.DeleteResourceToWastebasketCommand#sap.com/irj#com.sapportals.wcm.command.DeleteResourceToWastebasketCommand#E005007#10396##n/a##b70095bb5f5911e4a798000002ab5054#SAPEngine_Application_Thread[impl:3]_58##0#0#Error##Plain###RID '/documents/- <Folder Name> is locked by <'User'>#
The wastebasket service has failed to startup due to a mis-configuration.
Fixing the Wastebasket Service & Enabling Folder Deletion
Any configuration which is causing the wastebasket service startup fail needs to be removed and subsequently corrected.
After making the required corrections a restart of the system should be performed so the service can start up accordingly.
Once the wastebasket service is running it should then be possible to delete the resource as desired.
