Java ClassCastException in Web Dynpro in RFC import

[Former Member]

Hi,

I have done a copy of the RFC module: CRM_ORDER_READ in CRM 5.0. When I try to import the RFC I get a ClassCastException in Web Dynpro.

The following comes with the Java Exception Message:

RFC import failed:. Cause: class.java.lang.ClassCastException:null

at com.sap.dictionary.tys.mdi2metamodel.R3ToMetamodelDictionaryConverterWithNestedStructures.java:237

When I look at the import procedure being performed, it looks like all the export parameters are being imported correctely, but when it comes to the import-parameters with the first structure: IT_HEADER_GUID things seams to go wrong. Has anyone seen this problem before?

Hi Kristina

Don't use line types in your RFC's. These are not supported in the Java world. Please see note 1128296.
