problem with Type Reference "TYPE' in JCO

Hi All,

I am facing a weard situation when i am creating a custom RFC function module. This FM is called by Java program with JCO. But, if i define the FM parameters with Reference type as 'TYPE', the Java application is not able to get the data. But the same time, if i declare the parameters with 'LIKE', it is working successfully.

Can anybody advise me, why it is behaving differently? Is the problem with JCO which is not able to recognise the 'TYPE' reference or from SAP side?

And, any solution to use 'TYPE' reference successfully?
