I am also trying to do something similar. I need to be able to add service items to a JE. I have followed the directions suggested: go to the JE, go to the reports tab, go to transactional journal, and I am able to customize this report to show the 'items', however it does not let me edit from this report. It is merely a report with no editing capability. Is there a workaround to be able to add 'service items' to a JE?
