Customer field in QM11 transaction

Hi gurus!!!

I have implemented QQMA0001 enhancement in order to manage some customer fields. I have defined ZAQMEL append within QMEL table and I am able to insert and modify data in these customer field.

Now my problem is that these customer fields are no available in QM11 transaction.

Where should I inform these fields in order them to be available within QM11 transaction?

Thanks in advance.
