Import mass transports vs import single transports

Hello, in our company we have defined a rigid procedure to transport R/3 change request to our production system, now we are thinking to change this procedure.

We have checked again the online help about TMS, and we can read that SAP talk about two strategies to import request in R3 systems using TMS queues.

SAP say:

You can choose between two procedures when you use import queues to perform imports:

You can import mass transports into your systems. This procedure imports all requests waiting for import in the queue. All requests are imported into the target systems in the order they were exported. This minimizes the risk of errors in the target systems caused by requests being imported in the wrong order, and the risk of objects being missing in the target system.

Mass imports are particularly well suited for the quality assurance system and production systems in the implementation phase of a project.

You can import single transports into your systems. This procedure makes a selection of requests from the import queue and imports them into the target system. The other requests remain in the import queue, where you can choose to import them later, or not at all. Single imports are the most flexible method, however, they demand more administration.

In our system we can no use the mass imports because in the production transport queue, every day there is many requests that was not tested still in QA system these requests can not be imported in production system yet, and then, we must use import single transport.

We must use import single transport , but also we want to assure the consistency of the production system, and to minimize the errors due to a transport request in wrong order with the same or dependent objects or errors due to transport request with partial object.

Nowadays to assure the consistency in the transport process, we donu2019t allow to transport a request to the production system, if there is any requests not imported ahead in the queue that have the same objects or objects that belong to the same functional module.

Our development department request us to relax this procedure and to allow more transports of request to the production system, and then now we are thinking to change de prodedure, and we want to know how other companies work with the transport system, or if there is any SAP expert recommendation about this.

Does everybody allow single transport request to production system? If yes how they control that the request donu2019t cause problem due to other request that still are pending of transport, really does everybody respect the transport queue order of the request in the single import??

Thanks in advance for your help

best regards
