The process of semantic web service composition arranges several web services into one composite service to realize complex workflows with an exploitation of semantics. This paper proposes an approach to automatic semantic web service composition. Its advantage is good scalability regarding the complexity of user constraints and pre/post conditions. Based on these conditions it propagates the value restrictions constraint from the user goal through the overall composite service. The resulting plan depicts all the possible branches of the workflow leading to a goal. This includes the automatic generation of the conditions deciding which branch will be chosen during the execution. Finally, our approach exploits available data which can be used as input parameters for web services. If these are not offered, it searches for a web service producing them.
