If an RPC/encoded Web method has no input or output parameters, it cannot be mapped to a proxy table. A proxy table for a Web method without parameters would have no columns. A table with no columns cannot be created in Adaptive Server Enterprise.
Modify the Web method to include an input or output parameter.
Only simple types are mapped to columns. Complex types or arrays used in RPC/encoded Web methods result in the Web method not being mapped to a proxy table.
Modify the Web method to use only simple types and arrays.
