Hi,



I have created a dll which encapsulates SAP custom BAPIs/RFCs pertaining 

to Plant & Maintenance module using SAP DCOM connector. This BAPI I am 

invoking from a WebService (ASMX Page) using COM Interop and exposing it 

as a Webmethod. One of the BAPI is failing as it expects a SAP structure 

type to be passed to it as one of the parameter. Tried passing an object, 

recordset, dataset, dataview, yes a varianttype as well but unfortunately 

none of them worked. Getting the error as "The method return a COM variant 

type that is not interop compatiable."



Would appreciate if any one call help  me out with this as my project is 

struck bcos of this.



Cheers!
