Field help (CPTTYP) 

The category is set up in the document type.
The accounting document category can take the following values:

Actual

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

Active simulation or Inactive simulation

The simulation document, once activated, is also integrated with the inquiries and print-outs. It can be converted into an actual document or de-activated in order to become an inactive simulation document (that is to say it is not visible in inquiries and reports: for instance, the physical 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 status of the simulation journals is changed using the process of the Accounting functionality.

SEEINFO Any recalculation of the same Purchase Accrual/Sales Accrual, for a period identical to or different from the initial calculation, will cancel the documents in active simulation mode created at the time of the first calculation, and will generate new active simulation or actual documents according to the generation type chosen.
