JCO_ERROR_CONVERSION

[Former Member]

Dear Experts,

I am using WebDynpro based ESS in EP 6.0 SP18 and ECC 5.0. If I

access any application that is baed on WebDynpro ESS, I am getting

the following error.

com.sap.mw.jco.JCO$ConversionException: (122) JCO_ERROR_CONVERSION:

Cannot convert a value of 'EXT_SERVICE' from type java.lang.String to

STRUCTURE at field TABNAME

at com.sap.mw.jco.JCO$Record.createConversionException

(JCO.java:11530)

at com.sap.mw.jco.JCO$Record.setValue(JCO.java:13534)

at com.sap.mw.jco.JCO$Record.setValue(JCO.java:14434)

at com.sap.mdi.ddtypes.DDFactory.getDDObject(DDFactory.java:400)

at com.sap.dictionary.runtime.mdi.DataProvider.getDataType

(DataProvider.java:282)

The Jco connection are setup correctly and I am able to test them

without any error. Single Sign On is working with out any problem

between Portal and ECC 5.0.

Please advise.

Thanks,

Dear Vik,

Thanks for the excellent references. Basic SAP given FlightList example also giving the same error. This must have been related to SAP Note: Note 843985 - JCO_ERROR_CONVERSION in the adaptive RFC. I am waiting for SAP to give some solution right now.

Once again thank you very much
