SAP PI Transport process using CTS+ - DEV-> Qualilty-> Production
I have three environments in SAP PI- development, quality and production environment. We have separate SLD's for all three. We follow a CTS+ methodology for transports.
The method we currently follow is that when we transport from Development to quality, we provide a Transport number to basis team(development TR number) and then when we transport from quality to production we gain create a new Transport number in quality and then send the same to Production and not the development one.
We do have transport routes and transport targets created for both like
I have been asked to give a justification that why we follow Dev->QA->Prod i.e. different TR concept rather than Dev->Prod i.e one single TR.
Kindly tell me the best practice and supporting document if any which I can provide as my justification..
