Show "currency exchange rate" as a page field

I’m doing an extension of the “Vendor Ledger Entries” page and I want to add a field that shows currency exchange rate amount, based on the “Currency code” field that already exists on the page. Is there a way to achieve this? I’m totally new to Business Central so I have no idea where to start

Yes, it is possible, e.g.:

  • creating new page field
  • show value calculated by function
  • create function to calculate the amount.
    For better usability do the calculation and visualization asynchronously.
