Document SimulationYou can simulate a
captured document before you actually post it. During simulation, the document
goes through all the checks required for posting (see also
Control Functions for
Entering and Posting Documents).
When you simulate a document, automatically generated items, such as input tax and tax on sales and purchases, are displayed.
You can use the following views to display the captured document:
● Entry View
● General Ledger View
● Entry View:
In the entry view, you obtain an overview of the line items already entered, and you can check whether they are complete and correct.
For more
information on the procedure, see
Simulating Documents
in the Entry View.
● General Ledger View:
In the simulated general ledger view, the document is displayed independently of ledgers. With the standard settings, you always receive a view of the leading ledger. From this screen, you can simulate a view of the update to a particular ledger by specifying that ledger.
When you use
document
splitting in General Ledger Accounting, you can call up the expert mode
from the simulation of the general ledger view. In the expert mode, you obtain
detailed information about the split document as well as about the document
splitting rules applied. Furthermore, it allows you to view the Customizing
settings for document splitting specific to the business
transaction.
You can also use report FAGL_SHOW_SPLIT to call the expert mode for documents that have already been posted.
For more
information on the procedure, see
Simulating Documents
in the General Ledger View.

Simulation is not available in all functions for entering a G/L account document. For example, it is not available in the standard functions (Enter General Posting or Enter General Posting for Ledger Group).
In document entry, you have entered the document header and at least one line item. In the menu, choose:
● Document → Simulate for the entry view
● Document → Simulate for the general ledger view
