Whether you can bank or not depends on the following:
What your use year month is. (This determines your banking %)
What is your total contract size (All add-on's for this contract included) (This is what the % is calculated on) EG 150 OKW + 50 BWV = 200 pts. If currently in 50% window, then 200 x 50% = 100 pts. maximum bankable.
Have you already banked any of your points. These are subtracted from maximum bankable. EG you already banked 50 pts, then maximum bankable in above example is 100 - 50 = 50 pts maximum bankable.
You're outside the 30 days so you're OK there, the points will not go into holding.
