Fill the grid with digits 1 to 9 so that each row, column and boldly outlined 3x3-box contains each digit exactly once. Clues outside the grid give the sum of the digits between 1 and 9 in the corresponding row or column. For the clues outside and inside the grid, digits 0-9 have been coded with letters A-J. Same letter means same digit, different letters means different digits. Multi-digit clues may not start with a 0. Some digits have been replaced by “? “, there is no additional information given about these.
Solution code: Row 8, Column 2

Somebody told me he needed heavy T&E. Although the puzzle is quite hard, this is not necessary and I'd like to encourage everybody to find the logical way through the puzzle. However, I have added a hidden comment with a complete logical path.
