WSO2 SAP endpoint property file - searching for wrong file name and path

Question

I have "export" proxy service which aims to "obtain" sequence. The sequence points to ${server}/services/sapBapi or "sapBapi" proxy service. The "sapBapi" proxy service points to gov:endpoints/sapbapiendpoint.xml endpoint, where is the concrete address: bapi:/abc

I have abc.dest and abc.server property files with SAP endpoint parameters on path $WSO2_HOME/repository/conf/sap according to official documentation here

When I want to use "export" proxy service and send data, I will find this in logs:

DEBUG - Started sending message to uri=bapi:/abc/services/sapBapi/services/export {org.wso2.carbon.transports.sap.SAPTransportSender}
WARN - JCo configuration file for the destination : abc/services/sapBapi/services/export  does not exist - Please specify the JCo configuration in $WSO2_HOME/conf/sap/abc/services/sapBapi/services/export.dest or abc/services/sapBapi/services/export.dest {org.wso2.carbon.transports.sap.CarbonDestinationDataProvider}
ERROR - Error while sending request to the EPRbapi:/abc/services/sapBapi/services/export {org.wso2.carbon.transports.sap.SAPTransportSender}
com.sap.conn.jco.JCoException: (106) JCO_ERROR_RESOURCE: Destination abc/services/sapBapi/services/export does not exist

When I put export.dest file to path $WSO2_HOME/repository/conf/sap/abc/services/sapBapi/services/ , then it works perfectly.

My questions:

1. Why is it using proxy service name ("export") for the .dest property file in described case?
2. Why is it searching for .dest property file on path $WSO2_HOME/conf/sap/abc/services/sapBapi/services/ instead of $WSO2_HOME/repository/conf/sap/ ?

WSO2 version: 6.5.0

I don't know WSO2 Enterprise Integrator, but obviously an instance of class org.wso2.carbon.transports.sap.CarbonDestinationDataProvider is the registered DestinationDataProvider at the JCo runtime. This is the instance that decides alone from where to obtain the logon parameters for a JCoDestination based on the destination name string that it gets from the JCoDestinationManager .

From your example error message, this destination name string seems to be "abc/services/sapBapi/services/export" in this case for which the org.wso2.carbon.transports.sap.CarbonDestinationDataProvider is searching a property file with name abc/services/sapBapi/services/export.dest

I hope this info will help you to adapt your code/configuration to fit your expectations.
