Hello,

We would like to perform replication only when needed to avoid any load on the source systems. We see a new option in replication options called 'On Demand'

What is the procedure to trigger on demand delta replication?

We have sceanrio of ERP --> ERP on HANA

Best

Hi Navjot,

On Deman can be used to load the data whenever it is required. For this I think you have to manually load.

Hi Navjot,

the option "On Demand" don't suite for your. Un forunately it's not documented in help, but it's a case when the replicatin is triggered from outside. I think, for you it's better to create configuration as usual and switch off/on when you need.
Of course it depend from what scenario would you like to implement.

The best option is to suspend the replication process and start as on need basis. This will retain all the logging tables only delta will be pushed across when resuming the replication process.

You can do on demand replication using the " load Table" option in data provisioning. Every time you need to load, just remove the table from the config, add relevant filters for the table in LTRS, and then re-add the table again.

This will do a load from the table directly, rather than referring to the log tables, and you will need to apply filters to avoid loading duplicate records in target.
