Environment

Release : 12.2.0, 12.1.2

Component : AUTOMATION ENGINE

Cause

This is caused by a defect where there was an incorrect order of operations in the code:

delete 
truncate 
commit 

which should have been

delete 
commit 
truncate 

Resolution

The utilities should be updated to the latest service pack for the version being run; for example, if the utilities are running on 12.2.0, they should be updated to the latest 12.2.x service pack.

This was fixed with the utilities for 12.1.3, 12.2.1, and 12.3.0.
