SAP Error Message - Details

• Message number: 145

• Message text: &1 &2 (&3) is not a business partner

What causes this issue?

You have entered a name or number that does not exist in the business
partner master data. This can be for the following reasons:
The person, organization, or hierarchy has not been defined in the
master data.
The name or number represents a partner who has been defined in an area
other than business partner master data, for example, in Human
Resources.

System Response

The system cannot determine the business partner.
For example, the system cannot recognize an employee's user ID as a
business partner unless the employee has been entered as a business
partner, and the master data includes his or her user ID.

How to fix this error?

Create a corresponding business partner with the partner number or a
group hierarchy with the description &V2&.
If you use a name or another number as the partner number:
Check whether the entry has been maintained in the master data for this
partner.
If you use a user ID, check that it is maintained in the <LS>User</>
field for the role <ZK>Employee</> in the master data for the partner
you want. You can only maintain this field if personnel data is not
delivered by a human resources system.
If your entry is for a group hierarchy that the system cannot find, use
the input help.

Procedure for System Administrators

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