Good day,
I would like to get some help with the next.
A B C D E
F
1 2 2 1
2 1

1 A are booked pieces
2 B are additional pieces
3 C are actual pieces
What I would like to get are
D booked pieces left on time
E Any additional pieces loaded
F If a offload occurs the pieces that's offloaded
The problem I get stuck with are if any pieces are offloaded, it should be
subtracted from A completely ignoring the figure in B, and if the actual
pieces in C are higher than the pieces in A it should be in E
