MM custom screen in MM17

Hi all,

I have a requirement to add the custom fields to MM 17 transaction. I referred to SDN and the SAP notes. Accordingly i have implemented BADI and user exit. All my custom fields are in MARA table but in the custom view or tab. When i go to MM 17, i could see the general basic data and other tabs. the values are not updated in the custom fields. is it because we do not have the custom screen in the MM 17? If so how to add the screen to MM 17. Or am i doing something wrong.

I getting the below message:

Trying to create: XXX ____ ____ ____ __________ ____ __ ___ ___

The material cannot be maintained since no maintainable data transferred

Trying to change: XXX ____ ____ ____ __________ ____ __ ___ ___

Thanks in advance.
