Trying to add SSRs to all passengers on a large group booking using the SpecialServiceRQ method, but getting an ERR.SWS.CLIENT.VALIDATION_FAILED response for the 50 passengers on the booking.
The documentation for the SERVICE node suggests that it can be repeated up to 99 in the one request. After some experimentation then the service will return a good response with up to 47 repeats of the SERVICE node, after that the ERR.SWS.CLIENT.VALIDATION_FAILED response is given.
The request being made is

I've tested this and obtained "Request exceeded maximum Host Command length". That would mean that native Sabre won't take such a long concatenation of SSRs, thus you should split your request as advised. This is a low-level service so it's basically just sending a blue-screen format behind the scenes.
