Where is the data in my new added field stored?

Hello,

I've added a field to my BSP form in sm_crm. It is called 'Configuration Item' and the technical name is /BTADMINH/EXT./AICRM/CUSTTXT01.(See screenshot)

I now want to debug to find out in which table my new field is stored. But I don't know where to start. Can anyone point me in the right direction?

Thanks in advance.

Cheers,

Tim.
