If you need to perform a system refresh, an OS or DB migration, or if you want to avoid the initial load process, the following options can be used:
- Start Recording
- Start Replication (w/o Load)
These options are only available by default using DMIS 2011 SP13 and onwards. To display these options in older support packages, you must set the user parameter SLT_EXPERT to X in transaction SU3.
For more information, see SAP Note 1933605 and the guide Resuming Replication Without Initial Load After System Refresh or OS/DB Migration on help.sap.com/sapslt.
The following describes these options:
Start Recording
It only creates a logging table and a trigger in the source system to capture all changes of a table.
Start Replication (w/o Load)
It starts the replication of a table that has only been recorded. There is no initial load. Therefore, only changes registered in the logging table are transferred to the target table.
You can find more information in the Resuming Replication Without Initial Load After System Refresh or OS/DB Migration Guide.
