Field help (GAFTYP1) 

What is defined here is the type of document and the journal that will be used for the generation of the actual and simulation journals.

They can be different from the template journal. In effect, for reasons of journal consistency, it is possible, for instance, to decide that no template journal shall be created in a sales, purchase or other... journal. Yet, those journals generated by the recurring task can be invoices, cash collections, miscellaneous operations etc.

The document type and journal proposed by default are those of the template journal.
