When
you select the Source data column option, a dialog box appear.
The Columns required
section lists relevant data required for the foreign exchange
conversion using a single currency. Net (GBP) and VAT (GBP)
options appear with an active check box and will be selected
by default. If you do not require conversion for one of these
values then you can uncheck the relevant box. However,
in order to perform the conversion, you must have one of these
selected.

You will need to identify the column header from the
drop down menu that matches each of the items you have selected:
Net (GBP) derived from:
Select the relevant column in your source data that contains
the non-GBP Net values that need converting.
VAT (GBP) derived from:
Select the relevant column in your source data that contains
the non-GBP Net values that need converting.
Exchange rates found in:
Select the relevant column in your source data that contains
the exchange rate that should be used to perform the currency
conversion into GBP.
Once you have finished setting up the requirements for
the multiple currencies conversion, click on the Save
currency button.
You will now be taken back to the Map data tab. If
you have set up a currency conversion for the VAT amount and
the Net Amount, then you will see that both of these column
headings have also been mapped. These are the mandatory
headers that must be mapped in order to proceed with your
VAT calculation. You may now map further headers to
your data columns if you wish to.
If you only set up a currency conversion for one of the mandatory
headers (either VAT amount or Net amount) then you will need
to map the remaining mandatory header. You can also choose
to map further headers if you wish to.

Once you have finished mapping your column headings,
click on the Close and continue
button. You will now see a list of all the headers you have
mapped. For the column headings that you have set up
the FX currency conversion on – you will see the conversion
type description displayed.

AlphaVAT defaults to including all mapped headers in
the VAT calculation reports. But you can use the toggle
in the Show in report?
column for any headers that you do not want to include in
your reports.
Once you are finished, click on the Save
and map files button. You can now move onto any other
data files that you have uploaded, to map your column headers
and set up foreign exchange currency conversions where needed.
