It is not quite clear and I am not sure what you mean by "club", but presuming that you are flying on two separate tickets: #1: UK-AMS and then #2: AMS-DOH-JNB. KL will not check bags across separate tickets. Thus, you will need to meet whatever the requirements are as the time of your travel to enter the Netherlands, claim your luggage, take it to the QR counter and check it in there.
