Our client was thinking about synchronizing key business information across 1C system and SAP. Clients IT specialists raised the issue of using web services. Web services technology is commonly used by SAP and 1C and WSDL file is recognized by 1C as well as SAP. This means there must be a SAP Web Service and then 1C has to communicate with this Web Service in some language. But WSDL file in SAP does not include xsd-file. At the same time 1C work with single-file format of WSDL file.
