General ledger account used to handle m:n relationships in DATEV-FI for SAP Business One.
In SAP Business One you can create m:n bookings. However, DATEV can only process 1:n or n:1 bookings.
Therefore, you must use an interim account when you transfer m:n postings from SAP Business One to DATEV-FI.
Alternatively, you can use the Versino Financial Suite with your DATEV import/export.
