NH,
Good that you are able to reflect colors for the operations. When creating a decision step for a Resource chart, you have the option to choose the object you want to compare i.e. the object can be from a resource, product, order or operation. Each of these options provide various objects to compare from field selection. I suggested to use Product and the field AT104 / AT105, but you are free to explore and choose the best fit.
To answer your questions,
1. If you want different colors to show up for different conditions, you should use different decision groups. This is just playing with If, Else statements to perform desired sequence of checks.
EX:
Decision Group | Decision | IF | Then |
| 10 | 5 | AT104(Product) | Equal To | 'GREEN' | Obj ZOPR_I_1 |
| 10 | 10 | AT104(Product) | Not Equal To | GREEN' | Decision Group 11 |
| 11 | 5 | AT104(Product) | Equal To | 'RED' | Obj ZOPR_PC_1 |
| 11 | 10 | AT104(Product) | Not Equal To | 'RED' | Decision Group 12 |
2. If you have saved it once and assign a transport request, if you make further changes without backing out, it usually does not prompt you to save. In customizing the Planning Board Profile, you can always goto Table View -> Transport to add your changes to a transport.
3. I am not sure i can answer this but by using decision group - decision steps and assigning a unique graphical object, you can assign different colors to different products.
