Hi Anthony,
As i understand from the screen shot you have created the Quality plan hence in QP02 check with the below inputs i.e.
Plant and material
because if already created quality plan might not valid on what you have given input date
similarly if you are using ECM (Engineering change management) for Quality plan changes then only we will create a ECN (Engineering change note) by assigning the activity then we will make changes in the quality plan with reference to that ECN Number
so my suggestion to check with plant and material number
then check the validity in QALS table
