Requirement – The line-level data of the Advanced Intercompany Journals should be updated through CSV import
Solution – The lines of the Advanced Intercompany Journal Entry Line sublist are not keyed, therefore you cannot directly update specific lines. That is, there is no key field to map in the import assistant. To update journal entry lines, ensure you have exported all journal entry lines, make the necessary changes in the sublist lines, check the Overwrite Sublists box in the advanced options, and overwrite the whole sublist.
