SAP Error Message - Details

• Message type: E = Error

• Message class: WN - Plant master data maintenance (integrated)

• Message number: 666

• Message text: Business partner of plant &1 is not available in the target system

What causes this issue?

You want to distribute plant data using the data replication framework
(DRF).
The business partner that is assigned to this plant is not (yet)
available in the target system.

System Response

It is only possible to replicate data for a plant to a target system
where the assigned business partner already exists.

How to fix this error?

Transfer the business partner master data before you transfer the plant
data.

Procedure for System Administrators

The data transfer settings for business partners and plants must be
defined so that business partner data is transferred before the plant
data.
If you set up direct transfer for both business partner and plant data,
you can use optional parameters for retry for the plant implementation
and adjust the wait time so that the business partner data is replicated
to the target system before the transfer of plant data finishes.
