When generating a VAT return the transactions that it will look at are
- Sales invoices
- Purchase invoices
- Customer receipts
- Supplier payments
- Non customer receipts
- Non supplier payments
Journal postings do not appear in VAT returns so depending on the type of transaction this is for you will have to remove the journal and crate one of the above transaction types with teh VAT on it so it can be included in the VAT return.
Note - If you have ran the VAT return but not submitted it yet the details wont change automatically. You will need to delete it and run it again when ready to see the updated transactions pull in.
