 Journal codes can apply to a specific company, a specific site, or a specific group. This information is defined when the journal code is created but the selection window for this field (using the selection tool) does not take this into account. These controls are applied when you select or confirm the journal code. You can amend the journal code if an error message warns that it is invalid.
