Hey, 

Really new to this - so bear with me. 

I have table full of OrderNo. (Salesheader) 
Once a month - I need to fetch the related invoicing costs from a HTTP request.

Having trouble setting up the code as I keep getting all sub-table ordernumbers in the same request. Currently I have a UpdateTable and SalesHeader as a Subtable (Which is absolutly not needed and might not even be the way to go). 

Fixing the date for each request isn't a hassle at the moment - the issue lies within just fetching one specific record.OrderNo 

E.g.
Orders: 12345 & 6789

let currRec := Id;
for Id in 'SalesHeader' do
    do as server
        let url := "https://fakeadress.com/" + 'OrderNo';
        let APIKey := "XXX";
        let response := http("GET", url, {Authorization: APIKey,'content-type': "application/json"}, null);
let abc = response
this.('cost' := abc)
    end
end

This code executes twice with "https://fakeadress.com/123456789"
What I need:
1st request: "https://fakeadress.com/12345"
2nd request: "https://fakeadress.com/6789"

Is this possible or should I look for a workaround?

Thanks!
