For more information, see [GetUpdateData](/openspecs/windows_protocols/ms-wsusss/c28ad30c-fa3f-4bc6-a747-788391d2d964) in MSDN. The LocURI to get the applicable updates with their revision Numbers is `./Vendor/MSFT/Update/InstallableUpdates?list=StructData`. Because not all updates are available via S2S sync, make sure you handle SOAP errors. - For mobile devices, you can either sync metadata for a particular update by calling GetUpdateData, or for a local on-premises solution, you can use WSUS and manually import the mobile updates from the Microsoft Update Catalog site. For more information, see [Process flow diagram and screenshots of server sync process](#process-flow-diagram-and-screenshots-of-server-sync-process). -> **Note**  On Microsoft Update, metadata for a given update gets modified over time (updating descriptive information, fixing bugs in applicability rules, localization changes, etc). Each time such a change is made that doesn’t affect the update itself, a new update revision is created. The identity of an update revision is a compound key containing both an UpdateID (GUID) and a RevisionNumber (int). The MDM should not expose the notion of an update revision to IT. Instead, for each UpdateID (GUID) the MDM should just keep the metadata for the later revision of that update (the one with the highest revision number). +> [!NOTE] +> On Microsoft Update, metadata for a given update gets modified over time (updating descriptive information, fixing bugs in applicability rules, localization changes, etc).
