Question

Hi ,
Can you confirm online and offline scenarios are possible in MI . we are having NW 2004s here .
online : I want a purchase order number to be checked with the backend instantly?
Is this scenario possible  ?
Offline : should i replicate the data from the backend on to the MI client to do the check of a purchase order ?

Hi Abhilash,
You can do do both online as well as offline.
Online :-
You can do it by creating a generic sync application.
You need to create a remote enabled function module which will take as input a purchase order number and check it from those available on the system.
To know how to create a generic sync application refer the link : <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/21eba3a7-0601-0010-b982-92f1fca3258a">Generic Sync</a>
Offline :-
You can do it by creating a Smart sync Application.
Here you will have to create atleast two remote enabledfunction modules viz Getlist and Getdetail implementing the same functionality.
To know how to create a Smart sync application refer the link : <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/21eba3a7-0601-0010-b982-92f1fca3258a">Smart Sync</a>
The decision of choosing one among the two must be based on various aspects.
Smart sync/Offline is preferred for complex scenarios and those having a lot of data to be transferred between the client and the backend.
On the other hand Generic Sync/Online is preferred for relatively simple scenarios and those involving less amount of data.
I feel since you only need to see the availability of a particular purchase order in the backend, it is a very simple scenario and can be easily implemented via a generic sync/Online appln.
Not that it cannot be done through a Smart Sync/Offline appln, it can be done easily here also but its just that i think that it is not needed here.
Cheers.
