Understanding GUI/VAT GL Account Mapping
You set up GUI/VAT general ledger account mappings to specify all accounts for which you distribute amounts when you run the Tax Journal Entry program (P09106). During the GL distribution step of transaction entry, the system distributes input tax to the debit account that you specify, and distributes output tax to the credit account that you specify.
You use the GUI/VAT Account Mapping program (P75T012) to specify the accounts to which the system distributes amounts when you run the Tax Journal Entry program (P09106). You must set up in the GUI/VAT Account Mapping program all of the GL posting accounts that are specified in the GTxxxx AAIs. Enter D (debit) in the DC (debit/credit) field for accounts that you use for input tax. Enter C (credit) in the DC (debit/credit) field for accounts that you use for output tax. Do not map offset accounts.
The system saves the account mapping to the GUI/VAT GL Account Mapping table (F75T012).
