Entering GUI/VAT Information when Entering Journal Entries
You can enter GUI/VAT information for a journal entry immediately after entering the standard information if your system is set up to enable you to do so. To have the system display the GUI/VAT Multiple Transactions form on which you enter GUI/VAT information:
- Use the Journal Entries with VAT or Journal Entry program to enter the journal entry. 
- Your user profile must be set to TW (Taiwan). 
- The Link to GL field in the GUI/VAT Declaration Site program (P75T001) must be set to Y (yes). 
- The standard software journal entry program that you use must be set up in the GUI/VAT Document Type Format Code Setup program (P75T011). - If you use a journal entry program to enter both accounts payable and accounts receivable transactions, you must set up the entry program for both types of transactions. 
- Your authorization code in the GUI/VAT User/Declaration Site Mapping program (P75T010) must be the same as the authorization code associated with the transaction type for the declaration site. 
- Corresponding versions of the journal entry program and the PO-GUI/VAT Transaction program (P75T003) must exist. 
You must also complete the setup in these programs:
- GUI/VAT GL Account Mapping (P75T012). 
- GUI/VAT Tax Type Mapping (P75T008). 
- GUI/VAT Prefix Setup (P75T006) if the journal entry is for a purchase transaction. 
You use the Get Number menu option in the GUI/VAT Multiple Transactions form to assign a GUI number to a journal entry. You assign numbers only for those transactions for which output tax applies. You must set up a segment of numbers in the GUI/VAT Number Register - Sales program (P75T002) to use for journal entries before you can assign GUI numbers to journal entries.
You can also enter additional lines when you access the GUI/VAT Transaction program from the Journal Entry program (P0911). To add additional voucher lines, enter a plus sign (+) as a suffix in the Explanation field in the Journal Entry program.
