How to enhance ICCMP_AFS_HIS?

Hello Experts,

Hope you are doing good.

I need your help. There is an assignment block in the component ICCMP_AFS_HIS I want to add new fields to that AB. But, the underlying object is a view object without any relationships.

Can someone please explain the actual/recommended procedure to add new fields to the AB (without using AET, because the fields are already existing in the Database in some standard and custom tables)?

Thanks a lot in advance!
