The program uses this table to provide VAT specification on statistics windows and on printed documents.
The program summarizes all sales or purchase lines with the same VAT identifier and VAT calculation type in orders, invoices and credit memos and presents the totals in the VAT Amount Line table. For the US sales tax the statistics windows can be modified to show a tax specification line for each Tax Group Code instead of for each VAT identifier.
Note that the totals are not actually stored in this table. The data only exist temporarily.
You can modify a VAT amount line before the original sales or purchase lines are posted.
