The category is set up in the journal type.
The accounting journal category can take one of five values:

Actual:
The actual journal can also be viewed and printed (GL, Balance, etc.). The document is integrated into the balance when said document is saved.

Active simulation/inactive simulation:
Once activated, the simulation journal is also integrated to the inquiries and print-outs. It can be converted into an actual journal or de-activated in order to become an inactive simulation journal (i.e. it is not visible in inquiries and prints: for instance, the stock count postings).
SEEWARNING A period of a ledger type cannot be closed until the simulation postings have been either converted to actual postings or cancelled. The change of status of the simulation journals is made using the processes in the accounting functionality.

Off balance sheet:
The off balance-sheet journal can only be posted to off balance-sheet category accounts (via the account classification). It is generally used to track financial commitments.

Template:
The journal template can be used as the basis for the generation processings of actual or simulation entries (e.g. generation of recurring entries). It is not integrated to the GL accounting.
