default value in a mandatory field of t-code IE4N

<modified subject line>

hi everybody

in transaction IE4N, I must default the value of cost centre based on the equipment input but the problem is that the field cost centre is mandatory and that field only appears after inputting the movement type.

So first input equipment

Secondly input movement type

Its only then that the field cost centre appears and its mandatory and I really dont know how to handle given the fact that the field cost centre is mandatory

thanks for your help
