Smart synch request to backend

Hi,

I have created a General synch application and I can handle nicely what to download from the client side. Example: if I specify 175 for vendor number I get only one row back with the 175 vendor, if I specify 'Roger*', I get back about 40 rows.

Does the same can be done in smart synch? May I specify a value to be downloaded on the client (for example a text field for vendor number, and only this vendor will be downloaded to the client), or this is possible only in the snchBO where you can specify filter criteria? If it is possible which Java class would you use to set the filter criteria? Example code if possible would be nice.

Thanks in advance.
