This includes updating the account on the line item of a journal entry. However, there are a few things to keep in mind: 1. While the official documentation states that you can only add new lines or overwrite all lines, in practice, you can update specific lines by referring to a unique line id. 2. Be aware that updating journal entries may unapply payments if these entries have participated in such a process. 3. You can use a saved search to identify the records that need to be updated, download the results into a CSV file, and then upload this CSV to update the records. 4. For intercompany journal entries, it seems that you can update values in existing journal entry lines using your own CSV import, but this might not apply to intercompany journal entries. Please note that all these operations should be performed on entries that are in an open period.
