SmartSync API +Persistence API in MDK2.5 SP13

[former_member207329]

Hi , in the MDk2.5 documentation there is a important alert:

"The Persistence API must not be used in MI applications that use the SmartSync API. Please also check the latest SAP Note 717510 for restrictions"

If I use SmartSync API in a SmartSync application, how do to memorize the data (of the syncBo used in the synchronization) for offline mode? With File I/O and custom API?

best regards

hello rocco

> "The Persistence API must not be used in MI

> check the latest SAP Note 717510 for restrictions"

the SmartSync API handles the insertion, update and

deletion of your SyncBo instance when you access them

thru a specific SmartSync APIs. the SmartSync layer

also handles the delta data handling on your behalf.

ideally, you can implement and use Persistence API in

case when you have a hybrid application (GenericSync +

SmartSync). however, there are several factors that

should be considered when implementing the interfaces.

Hi Rocco,

Are you asking how do you use persistence on the client side for SmartSync Applications?

I have answered a similar question in a different thread.

I hope this helps,

Thanks all.

But the my very question is: after syncronization and after the my SyncBO has been unloaded in local MI Client (pda or other) I can read/modify/delete the data in SyncBO without save data in local db(on pda o other)in offline mode and in a second time syncronize the delta?

The SyncBO (your structure and your data)is serialized in automatic on device (after syncronaze) and I work it with SmartSync API? Not necessary save data in db layer?

Hi Rocco,

I don't understand your question. Could you rephrase it?

If syncronize and download mySyncBo in a device,I can modify/delete the data (es:name,qty,price etc) of the mySyncBO? Not necessary ,before, save the data of the mySyncBO in the local DB (es:db2e)?

I don't understand because is not possible use Persistence API with SmartSync API.

Hi Rocco,

No its not necessary to actually save anything, when you modify or add a syncBo data is automatically stored in to your persistence layer(DB or file). You will use the persistence api to query your data.

Hi Wael Aoudi, thanks for your attention.

When I install Me Client I have to configure the persistence layer?

[Former Member]

No you dont. Its all automatic, but if you want to use the DB you will have to install it through the Web console otherwise you can use the default File I/O

Hope this helps,

(dont forget the rewards and if your question is answered you should close the thread)

Thanks,

hi Rocco,

in Smart Sync application, Your BAPI+SyncBO takes care of it.

Refer MDK - help. it will give all answers you need regarding this.

Hi Rocco,

Smart Synchonization is build on top Generic Sync and Persistance. It is the responsibility of Smart Sync to manage persistance.
