While importing Web Service, the reported exception is due to Plex object name length.
Plex supports object name up to 32 characters. Within Web Service WSDL, there are couple of objects whose name is greater than 32 characters and Plex fails to create those objects within Plex repository.
For example in provided WSDL – one of the object name is – ‘TotalReturnSwapCouponRateSchedule’, that has length of 33 characters.
Plex only supports 32 character long object names, so considering this WSDL object name length should be compatible with Plex object name length.
