Reproducing the Issue

  1. Login to SAP Cloud for Customer.
  2. Go to Customers workcenter.
  3. Open Accounts facet.
  4. Find and open Account XYZ.
  5. Update details like name, email click Save.
  6. Login to S4 Hana system and check the received message of relevant customer.  
  7. The error message "Customer XYZ Already exists" is shown.


One of probable root cause is, you have set the action code in Cloud Platform Mapping(CPI) or Process Integration(PI) to 04 (create if not exist, else update).

Create/Update handling happens in S4 Hana system itself and hence no additional handling required in CPI Standad iflow.


Kindly unmap action Code in CPI & redeply the changes.
