I have the following problem, is required to make a validation on the Tax Number field in the Identification tab. I searched for Badis or exits without success.
Anyone knows if there is any other way to do this validation? I meant, maybe there is any trx where some fields validations are include
I know little or nothing of CRM.
Any help is welcome and if there is some missing information please let me know,
Thanks a lot,
Sorry for my english
