Problem with SAP R3 endpoint types when changing account password.
For SAP R3 endpoints with SAP basis component version as 750 the SAP Account passwords are converted to uppercase.
But they should not be converted because since SAP basis component version 700, the account passwords are case sensitive.
This is a workaround.
As the calculated SAP basis version is NOT equal to or higher than 700 (due to a wrong calculation in this case) then the SAP R3 java connector plug-in can consider the convertPasswordToUpperCase flag.
So copy the SAMPLE.connector.xml to connector.xml into the <Connector Server Home>\jcs\conf\override\sap folder and
modify this <Connector Server Home>\jcs\conf\override\sap\connector.xml file to change the flag from true to false as following:
Then restart the JCS service.
