====== How to Mantain VAT in Invoice Lines Manually? ======

By default existing VAT rules are applied automatically while adding product with VAT in Invoice line.

**To edit VAT settings per Invoice line manually:**

  - Find in **‘Invoice lines’** grid the columns which display & control VAT settings. They are: {{ :userdocs:travelwise:calculations:vat:vatintw10.png |}} As soon as the columns are located in the end of a long grid line, please drag and drop the columns closer to the beginning of line (in order to get a handy access to VAT columns).
  - Select the needed Invoice line.
  - In case you want to select the **‘VAT Product’** with exact rules for that destination, check that Invoice line has got a right destination and origin (values in ‘Destination’ and ‘Origin’ columns).
  - Select VAT Rule (VAT Product and Calculation Schema) from ‘VAT Product’ combo box.


:!: NOTES:
• It is allowed to select only those VAT Rules for a product which are specified in product's profile.
• Right after selecting VAT Rule, VAT becomes recalculated based on made selections.
• Destination and Origin affect only VAT rules applying. If VAT product and Calc schema is set, it is calculated correctly no matter of destination and origin.
• It is not allowed to set calculation schema until there is no ‘VAT Product’ selected, because it depends on the selected VAT.
