When using Initial Technical User (SAP_CUST_INI) in the newly requested P system, you cannot create user in Maintain Employees (Fiori app F2288), system error occurs as below:
Determination of Business Partner Role for category BUP003 failed or Interval EE does not exist for object BU_PARTNER BUCF.
SAP S/4HANA Cloud.
This error is raised because the Business Partner Configuration (SET content) is missing. This means that your P System does not contain the initial configurations from Q system (it is empty).
You need to complete the cloud standard SET content and cloud configurations for Business Partner. From 1908 release, the transport is completely customer managed. You have to initiate the first transport from Q System via "Proceed to Deploy phase" button in manage your solution app.
Please execute the "Transport Initial Change Project from Q-System to P-System". It is described at the Roadmap Viewer: SAP Activate Methodology for SAP S/4HANA Cloud
To understand the Q to P transport process for SAP S/4HANA Cloud please check our SAP Help Portal (see the Realize phase).
Note: To get rid of this issue, you have to initiate the first transport from Q System via "Proceed to Deploy phase" button in Manage Your Solution app. The initial transport will be deployed after business hours (11 PM Local time). Afterwards, you should be able to proceed.
