FWZZ - Tabstrib Asset Pool Data

Hi,

I am searching for any place to manipulate the field controls of this tabstrib. It only appears when using product category 42 bond with instalment.

I want to change some fields from "req. entry" to "display", or hide the whole tabstib.

Unfortunately I cannot find any customizing acivity to do this. How can I manipulate this "special" tab?

Kind regards

Frank
