Re: OO 9.x Documentation
Details on all OO out of the box operations is not something that is documented in one OO document.
For operations related to an OO integration to another application (ie: OO integration to HP Service Manager), there are specific integration guides with more information about the integration. Those can be found on the HP Support Portal, under Downloads > Product Manuals.
For documentation on the OO operations, use the online documentation. From Studio, expanding to a folder or an operation, right-click and choose the option to 'Generate Documentation'. This will bring up the online documentation provided for those operations.
