Make account notes editable in mobile device

Hello experts,

My question is related to mobility (CRM Mobile Sales).

We want to manage the 'Account Notes' based on the BP role, in mobile device.

The requirement is to have account notes editable (only account notes, not the master data) for 'Sold-to party' BP role in mobile.

SAP suggested to use the BADI - '/msa/badi_business_partner~change_end'.

I am not sure how to control the 'edit' attribute for account notes.

In the above suggested badi method, we have parameter CT_BUPA_NOTE (type - CRMS_BUPA_MOB_NOTE) for account notes.

How can we use this badi (parameter) to make the account notes editable in mobile?

In the structure 'CRMS_BUPA_MOB_NOTE', there is field called NOTE_MODE. Can this field be used to achieve this?

Please help to get the solution for this.

Thanks,

Sujeet
