Advanced InterCompany Journal
If the period is open and your role has Journal edit permission then you can edit it. Note that it is a “NO NO” subject for approved posted journals as per the GAAP and other compliance control. Also if your system is using a approval workflow for the journals then most likely workflow is locking the JE once approved and at that is the case even with right permissions you wont be able to edit an approved JE. To do that you need to modify the workflow and add an exception criteria for the lock state/action.
