Dear Rahul,

In the file <tablename>hdlr.c file, you have a function named <tablename>processRequests() which returns SUCCESS / FAILURE depends on the operation performed in the external application . If the external application fails to do the requested operation, then the external application construct a pdu with return failure with errorStatus and errIndex.

the function <tablename>ProcessRequests() also forward the result which is SUCCESS / FAILURE to the function ProcessRequests() which is called in the file pdureqhdlr.c file.

Here the value is assigned to the variable retVal which holds the value SUCCESS / FAILURE depends on the external application response.

If it returns FAILURE then it gets the value errStatus and errIndex values and sent it to the manager.

Kindly look into the function call ProcessRequests() in the function pdureqhdlr.c file at line no : 1013 which might help you to understand the scenario.

Hope this helps. Do revert back to us for further queries.

Thanks and Regards,
