Advanced BSP Programming

Brian McKellar is Development Architect for BSP and Web Dynpro ABAP at SAP in Walldorf. The past five years he has worked on the development of first BSP, and slowly moved over to Web Dynpro. He knows the complete BSP runtime better than the back of his hand, having worked on the development of large parts of it. Also, from handling problem tickets of years, there is not a problem within the BSP field which he has not seen at least once. Brian is also very active in SDN, and regularly contributes with technical weblogs on BSP. Thomas Jung is a solution architect on the SAP Technology Solution Management team, focusing on the SAP custom development tools, particularly as they apply to ABAP development or user interface technology. He is a frequent presenter at SAP events and can often be found on SDN. Before joining SAP Labs in 2006, Thomas was an applications developer for an SAP customer. He was involved in SAP implementations as an ABAP developer for almost 10 years.
