Which trigger to implement this?

I am trying to write code on Sales Order's subform;
Quantity Remaining = Quantity - Quantity Shipped - Reserved Quantity

Quantity Remaining is a new field I added by extending the Sales Line table and Sales Order Subform.

This value will be Quantity - Quantity Shipped - Reserved Quantity
However, Quantity Shipped only gets a value once the SO is shipped with the value in Qty to Ship.

I tried writing the following code on ExtendedSalesLineTable
trigger OnModify()

        IF rec."Quantity Shipped" <> 0 then begin
            recSalesLine.SetFilter("No.", Rec."No.");
            recSalesLine.SetRange("Line No.", Rec."Line No.");
            recSalesLine.SetFilter("Document No.", Rec."Document No.");
            if recSalesLine.FindFirst() then begin
                "Quantity Remaining" := (Rec.Quantity - Rec."Quantity Shipped") - rec."Reserved Quantity";

The problem is, I get Not Available in Rec.Quantity Shipped hence it always show me new field Remaining Quantity as 0.

    You are using recSalesLine and then modify without making any change on that record?
    Also why don't you use for example a codeunit with eventsubscriber when table sales line is modified?
