Thai localization document states that I should put branch number in Company ID field.

I can't post URL. It's in User Docs -> Finance -> Fiscal Localizations -> Thailand

However, this field is checking uniqueness across all contact. And it show conflict when branch number is the same.

For example, Company A has HQ and 3 branches: 00001, 00002 and 00003. (5 digit running number per RD requirement) and Company B has HQ and 2 branches: 00001 and 00002. When I put branch number in Company ID field, contacts app will warn that there are potential duplicate at branch 00001 and 00002 of both companies.

Is this expected behavior or I miss something.
