Abort action in a customized Business Rule
After looking for Business Rules where the Script Contains Abort or have Abort Action set to true, a Business rule was found that had a line of code as "current.setAbortAction(true);" which is aborting the action right before it sets the state of the change. This abort action is preventing the workflow from progressing.
