Customer Master and Contact Person is using BAS (Business Address Service) for many years by using central address tables. Business Partner is using BAS as well with own address data sets. This makes whole address management complex. With this blog post I would like to bring some light into this topic.

Workplace address: Mandatory for KNVK record

Click on Addr. Overview button, we can get below result.


How can we check at BAS table:


BUT020-ADDRNUMBER of BP-Org 396 = 43587

BUT000-PERSNUMBER of BP Person 395 = 43586

KNVK-PRSNR = 43584

KNA1-ADRNR = 43583
