Transports
(AS-ABAP) 
Use
Transports into productive SAP systems sometimes cause problems because they require a significant amount of time, especially if the transport is large. Therefore, optimizing transports can contribute significantly to increasing the availability of your SAP system.
You can find up-to-date information on SAP transports on SAP Service Marketplace at:

Activities
You can take the following steps to solve this problem:
· Make sure that enough processing power is available for background processing. Remember that a transport is a background job, which competes with other jobs for processing power.
To achieve this goal, do the following:
¡ Plan your workload so that, at the time of the transport, there are few or no background jobs running. Any background jobs that are running should have minimal processing requirements.
For more information, see SAP Notes 26966 and 50104.
¡ Adjust the SAP system operation mode for the period of the transports to favor background processing, using the Computing Center Management System (CCMS).

Modes.
· Use the new type of import available starting with SAP Release 3.1I, which performs the command TPIMPSYNC. This lets you perform transports without having to bring down the SAP system. By using TP IMPSYNC you can avoid problems with data buffering, so guaranteeing the consistency of your data.
For more information, see SAP Note 102069.
· Use "merged" transports. A merged transport has been consolidated to remove duplicate entries, so leading to more efficient processing.
For more information, see SAP Note 139513.
