Fields in Assigned objects for QM notification greyed out

Hello People,

I'm trying to create a custom object category(Material), I had followed every step. i.e define object category, implementing BAdi(BADI_QNAO_OBJCAT) and the configuring for a notification type.I have also added Material and Materail Description to structure QNAOS_OBJ_DATA_UI. And the same was reflecting in Assigned objects screen.

However, all the columns seems to be greyed out when i'm trying to create a notification. Am i missing something? or did i do something wrong?.

If any one implemented this enhancement please share your thoughts on this.

Please find the screenshot.

Thanks & Regards,

Praveen.
