How to can we make a field mandatory in BP creation?

Dear community,

we are trying to make a field mandatory at the BP creation, in our case, the "Tax registration nr".

I've checked the configuration and the BADI "Validate BP BADI" (CMD_VALIDATE_BP) from Business Context "Business Partner Core view", but we haven't fullfilled our requirement yet,

Have anyone had the same requirement? Is there any workaround for this?

Thanks in advance.

Best regards,

João
