Every invoice profile needs at least one transaction description so you can transfer data using the Transfer module. The default transaction is used in the Transfer job, but you can change this.
You can:
Mark a transaction description as the default standard transaction description
Select a standard transaction description in the Transfer job
Use one transaction description for each invoice type (when using a system job)
Note: Transaction descriptions are not used when you use XML output. Each invoice profile must still have a standard transaction description, but its content is irrelevant since it is not used.
