Symptom
Field 'CreatedByUser' in E-Mail templates shows the CB user rather than the Person's full name.
Environment
SAP S/4HANA Cloud Public Edition
Cause
This is currently a standard behavior.
Resolution
The E-Mail template is based on CDS view I_BILLINGDOCUMENT and currently CreatedByUser is always the technical user that is CB user ID.
Below are two example document objects where you see CB user:
There is no full name of user that created invoice available in billing output management.
Likewise, there is no full name of the creator of the Purchase Order in the Purchase order Email templates. Same is applicable for purchase requisition as well.
