Item No."does not exist

Note : SL is defined in Globals depending on Sales Line table.When I modify line of Item.GET('123456') any error occurs.

Item.GET(SL."No.");
Item.SETFILTER("Location Filter","Location Code");
//Item.SETFILTER("Variant Filter","Variant Code");
Item.CALCFIELDS(Inventory);
IF Item.Inventory <=0 THEN BEGIN
ERROR(Text045);

Have you assigned a value to your SL variable?

Try:
SL := SalesLine;

or just use SalesLine."No."

Make sure that SalesLine.Type = Item before you try to use Item.GET(SalesLine."No.").
