Hi Samantha,

I would say yes and developer should be able to do it as lot of user what to have Header and line details combined. In your case creating combined table with posted invoice lines and posted credit lines.

query 50000 "Item Sales Quantities"
{
QueryType = API;
APIPublisher = 'yourpublisher';
APIGroup = 'yourgroup';
APIVersion = 'v1.0';
EntityName = 'itemSalesQuantity';
EntitySetName = 'itemSalesQuantities';

dataitem(SalesInvoiceLine; "Sales Invoice Line")
{
DataItemLink = "Item No." = field("Item No.");
sum("Quantity");
}

dataitem(SalesCreditMemoLine; "Sales Credit Memo Line")
{
DataItemLink = "Item No." = field("Item No.");
sum("Quantity");
}
}

API development - combine data from 2 tables

you can create an API query in Business Central that combines data from the Sales Invoice Line and Sales Cr. Memo Line tables to calculate the net quantity per item.

Something like below.

query 50100 "Sales Net Qty API"
{
APIPublisher = 'yourPublisher';
APIGroup = 'yourGroup';
APIVersion = 'v1.0';
EntityName = 'SalesNetQty';
EntitySetName = 'SalesNetQtys';

elements
{
dataitem(SalesInvoiceLine; "Sales Invoice Line")
{
column(ItemNo; "No.") { }
column(InvoiceQty; Sum("Quantity")) { }

dataitem(SalesCreditMemoLine; "Sales Cr.Memo Line")
{
DataItemLink = "No." = SalesInvoiceLine."No.";
column(CreditQty; Sum("Quantity")) { }
}

column(NetQty; InvoiceQty - CreditQty) { }
}
}
}
