CPI-DS Rest Webservices - Query either selects from no object at all

Actual Error: Query <Transform2> either selects from no object at all, or its SELECT produces <1> columns while the query output schema specifies <0> columns

Found a relevant Note from SAP: 2568092

Cause: HCI DS does not know how to handle the response if they are not defined in webservices call. REPLY_SCHEMA under the imported Webservices call column tab, there is no respond schema defined. AL_ERROR_NUM and AL_ERROR_MSG are default HCI Data services schema.

Resolution: Check the webservices and make sure there is response from the webservices.

Have tried to do the mapping for AL_ERROR_NUM and AL_ERROR_MSG but not able to succeed. Any pointers ?

Thanks in Advance.

Regards, VK
