Systems, methods and computer program products for bookkeeping of download stamps are described herein. An embodiment includes augmenting database table (or mobile business object) metadata with a synchronization ('sync') key and assigning a unique identifier to each sync key. A sync key is assigned to one or more rows (or records) in the database table and a download timestamp is associated with each sync key. The embodiment further includes identifying a sync key associated with each row in the database table. Links between rows occurring in different database tables are maintained using sync keys. In this way, embodiments of the invention allow a server to record a download timestamp of database table subsets, where such subsets may include one or more rows in the database tables. This allows data to be downloaded by a client at subset granularity.
