Hi,
In the incoming days we will face the upgarde of our current SAP BI Platform (4.0 SP8) to next minor release (4.1). One of most challenging points is to ensure the proper behaviour of existing SDK customizations based on Report Engine API available at 4.0. I know that SAP is promoting use of Restful Web Services as a way to implement functionality previously delivered by JAVA API but my question is. Will current Report Engine API based developments work under in 4.1 release? In other words, has SAP planned an smooth transition from Report Engine API to restful Web Services scenario (compatibility scenario 
) or code will have to be completely rewriten 
?
Thanks,
