Appendix C – Notes on transaction entry for GAF

To comply with GAF generation requirements, please note the following when making data entries in Sage 300.

  1. All purchase invoices should be entered using a valid vendor code and BRN, and correctly set up Tax Group and Tax Classes.
  2. The JKDM GST ACT requires every invoice entry to include Tax information, regardless of whether the transaction is taxable. Transactions posted without Tax information create issues when generating the GAF.
  3. An A/P Adjustment does not have Tax adjustment capability. If there is any amendment to Invoices, a credit note or a debit note should be raised for GST Audit purposes.
  4. If an A/P Miscellaneous Payment is used, ensure that, after adding up the following fields, it is unique from other transactions.
    • Invoice Number
    • Payment Date
    • Remit-To (Remit-To Name)
  1. All sales invoices should be captured under a valid customer code, with the BRN number, and a proper Tax Group and appropriate Tax Classes setting.
