I am implementing the OTA_ReadRQ / OTA_ResRetrieveRS message pair and I have hit a problem. All the other messages I have implemented as paired messages EG: OTA_HotelAvailRQ / OTA_HotelAvailRS

I have tried to create the SOAP WSDL but I get an error from the client;

[faultcode] => SOAP-ENV:Client [faultstring] => Operation 'OTA_ReadRQ' is not defined in the WSDL for this service

It seems to me I need another definition for OTA_ReadRQ

So I tried duplicating the definitions, but it then said I have a duplicate “name”

I can’t find any information on implementing multiple definitions

<definitions 
name="OTA_ResRetrieveRS" 
targetNamespace="xx/resretrieve">`

The wsdl body which defines the elements etc is all fine and validates perfectly.

I can add the entire wsdl if that would help.

I believe the issue is with this section which defines the operation not have a matching definition for OTA_ReadRQ
