Example

In this code example, you copy the PK and S3 fields in the Source table for all rows where S2 equals A and add them as new rows in the Destination table. You use AddConstantValue method to give the field D2 the value X in the inserted rows.

local procedure CopyRows()
var
    dt: DataTransfer;
    src: Record Source;
    dest : Record Destination;
begin
    dt.SetTables(Database::Source, Database::Destination);
    dt.AddFieldValue(src.FieldNo("PK"), dest.FieldNo("PK"));
    dt.AddFieldValue(src.FieldNo("S3"), dest.FieldNo("D3"));
    dt.AddConstantValue('X', dest.FieldNo(D2));
    dt.AddSourceFilter(src.FieldNo("S2"), '=%1', 'A');
    dt.CopyRows();
end;
