Hi LInda - My apologies, I thought you were referring to the Journal entry grid when editing or adding a new journal entry batch. This screen shot looks like it is referring to the columns on the Journal entry list page. Journal is not a column option here (as you have already noticed :) ). As a workaround, you can sort the description column in the database view which contains the subledger name. In NXT, you can filter the journal entry list using the search function. I have removed the 'Already exists' label from your idea.
When I right click on column header row, I do not get an option for "Journal". I've attached a screen shot.
In the webview, the Journal column is in the Journal Entries grid. In the database view, if you do not see a Journal column then you may need to add the column by right clicking on the column header row and selecting 'Columns' from the menu.
You won't be notified about changes to this idea.
