How To Fix CVI_SYNC_TAX_NUMBER030 - There is a conflict between business partner &1 and vendor &2

CVI_SYNC_TAX_NUMBER030 - Overview

• Message type: E = Error

• Message class: CVI_SYNC_TAX_NUMBER - Error from synchronization of tax numbers

• Message number: 030

• Message text: There is a conflict between business partner &1 and vendor &2

What causes this issue?

There is a data conflict between the business partner and the vendor
assigned to it. The tax numbers are different for both objects.
If Master Data Synchronization is active and you process one of the
objects, the system overwrites the data for the other object.
This is illustrated in the following example:
Business partner 4711 is linked to vendor 0815.
The business partner is stored in the system without any tax numbers and
the <DS:DE.BU_NATURAL_PERSON>Natural Person</> indicator is set for tax
numbers.
The vendor is stored in the system with tax numbers but the <LS>Natural
Person</> indicator is not set.
If you process and save the business partner, for example, then the
system deletes the tax numbers for the vendor and sets the <LS>Natural
Person</> indicator.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check which object is the leading object and from which object the tax
numbers are to be transferred. To initially synchronize both objects,
execute the report CVI_SYNC_VEDN_TAX_NUMBERS (initial synchronization of
tax numbers for BP and vendor). For more detailed information, see the
corresponding report documentation.
