SAP Note 20021 - Inconsistencies in central address administration .

Symptom

When you print purchasing or sales documents, incorrect addresses are copied from the address administration for plants or sales organizations.

Cause and prerequisites

Inconsistencies in table T001W or TVKO.

Solution
The address number in table T001W or TVKO may only be used in one plant or sales organization. These address numbers point onto the address in table SADR. An address in table SADR must be unambiguously assigned to one plant or sales organization. You should maintain tables T001W and TVKO via the corresponding Customizing transactions OX10 or OVX5 and not via transaction SM31. You can maintain all addresses in SADR with transaction SAD0.
