Hi,
Somewhere exists a documentation (API docs) on CTS SDK. I've seen it long ago (5.3x era), you should find it on Powerlink or on subscribenet under DTS or ADTS or maybe under Documentations...
The short solution is:
ictsService.getNewTransformRequest(com.documentum.fc.client.IDfSession dfSession) which returns an ITransformRequest interface, on which you can set everything you need for a transformation request. On the end you should call ictsService.submitRequest(com.documentum.fc.client.IDfSession dfSession, ITransformRequest request, boolean notify_user, boolean synchronize, boolean deleteOnCompletion)
(ictsService should be an instance of ICTSService SBO)
