It depends on what you want to update and whether you want to be able to do this via SLM or via SMACC:

• Bulk update (a set of objects) with the SAME change can be done from within the SLM by multi select objects in 'search for <object> reports' then select 'edit...'
• Bulk update (a set of objects) with different change for any fields by exporting and then using Home->Import Data-> Update existing <ObjectType>. Please note that you may need to delete the data within the object before reintroducing it.

There is another way in achieving 'updates':

• by Integration Managers 'Snow XML' connector
• by using Import Service from "Snow License Manager Web Configurator" (see dialog tab 'Import Service' in after starting WebConfigurator.exe)
• by crafting SQL and DB-Jobs with usage of Snows-StoredProcedures like e.g. "PROCEDURE [dbo].[LicenseAddUpdate]"

Please note that this is not out of the box and the use of those procedures normally need prior retrieval of the input data needed for this procedure (not only feeding in the updated data) by prior usage of a corresponding 'Get' function/procedure. - e.g. "LicenseGet()". There are even some 'MultiEditAddUpdate' versions of the object-specific AddUpdate procedures which need to craft a predefined (xml-)structure before. Usually you need put this into some other sql-logic to do the lookup-/Sync-decision as to what object/attribute needs to be updated as well.

Due to the nature of this process, you may want to reach out to Snow Support or your provider to help.

The procedures Laura described will work unless you are talking about Objects in the sense of SLM Objects in the objects menu, not database objects in general.

SLM Objects do neither offer bulk update/delete as discussed here: https://community.flexera.com/s/feed/0D5690000AychEpCQI

Using the SLM Web Configurator tool, you will be able to import objects, as discussed here: https://community.flexera.com/s/feed/0D51r00008OqbImCAJ
