Provider has configured Black_SP fraud screening plugin. Trying to "Mark as fraud" Sales Order based on delegated plan, the following error appears:
ERROR: current transaction is aborted, commands ignored until end of transaction block
The issue is caused by #PBA-83858 "Duplicate key error when marking a reseller's customer's order as fraud using the BLACK_SP fraud plugin"
To workaround the issue, it is possible to remove the service plan from a plugin's blacklist and mark the order as a fraudulent.
After that, the plan will be automatically added to the list again.
If an order contains provisioning items for two service plans, then both of them will be added to the blacklist.
