Invoice integration - RFC gives Feldsymbol ist noch nicht zugewiesen. occurs. (Group: JCO_ERROR_SYSTEM_FAILURE) error

Hi,

I want to connect SAP ERP using RFC (JCO) to fetch invoice pdfs. I am using OTB parameters for invoice integration to connect to ERP. The connection fails giving below errors:

ERROR [hybrisHTTP29] [InvoiceDocumentController] Unexpected Error Occured while trying to fetch invoice data :: de.hybris.platform.sap.core.common.exceptions.CoreBaseRuntimeException: Backend System Failure Exception: Feldsymbol ist noch nicht zugewiesen. occurs. (Group: JCO_ERROR_SYSTEM_FAILURE) at de.hybris.platform.sap.core.jco.exceptions.JCoExceptionSpliter.throwCoreBase ``RuntimeSystemFailureException(JCoExceptionSpliter.java:180) ~[classes/:?] at Caused by: com.sap.conn.jco.JCoException: Feldsymbol ist noch nicht zugewiesen. at com.sap.conn.jco.rt.MiddlewareJavaRfc.generateJCoException ``(MiddlewareJavaRfc.java:618) ~[sapjco3.jar:20161208 0537 [3.0.16 (2016-12-06)]] at com.sap.conn.jco.rt.MiddlewareJavaRfc$JavaRfcClient.execute ``(MiddlewareJavaRfc.java:2033) ~[sapjco3.jar:20161208 0537 [3.0.16 (2016-12-06)]]

Is there anything we need to change in OTB parameters in hybris or at ERP side to make it work? The RFC destination connection works fine with order integration. Same RFC destination is used to fetch invoice details.
