When testing the SAP AFX Connector Update an Account capability, the connector test shows success but none of the SAP account attributes are updated in the endpoint.
This problem is caused by a misconfiguration. The parameter names being passed to SAP by the SAP AFX connector are in lowercase or mixed case. The SAP BAPI (Business Application Programming Interface) expects parameters to be in uppercase.
In this example, modify the parameter names to FIRSTNAME, LASTNAME and DEPARTMENT. Note that Username does not need to be capitalized.
