There is a Course for that, that shows you how to do the Sync

https://www.outsystems.com/training/courses/170/data-synchronization/

Basically using the 

Then you just need to call your sync client action that will deal with all the data inside. In this case, will update the storage with the data from the server and will remove/update/create the ones that were removed/updated/create in the storage on the server too.

And when you want to do any action you call the client action created to do the sync, instead of the local entity action.

Careful, there will be some times when you will need to adapt the logic to your use case. This is not straightforward.

ps: don't forget to put to true this sync configuration if you want to sync on login or on online, etc.

Check the OML

hello @Robo shankar ,

Check out this demo application.

https://www.outsystems.com/forge/component-overview/1638/offline-data-sync-patterns

In this application they implemented all the data sync patterns(read,read-write,1-many,r-w conflict etc.)

this will help you to understand how data sync work in outsystems.

HI Robo,

I hope you are doing well.

Thanks to Outsystems to make this process very simple, Simply right click on your local storage entity, and select and select Create action to Sync (Read/Write), then it'll automatically create few client actions and server action.

You can put your own logic there also you can control sync operation in OfflineDataSyncConfiguration client action or you can explicitly trigger sync action using TriggerOfflineDataSync client action 

Thanks
