As part of the logic FlexNet Manager Suite uses to identify imported records related to a single device, various assessments (called "Matchers") filter records fitting a specific set of conditions. During this matching process, if two devices on the same connection have the same serial number FlexNet Manager Suite will show only one device by default. In this situation, the device with the most recent inventory date is shown, while the other device is marked as a duplicate and not imported or visible in the UI. This logic caters to normal turnover of devices or machine re-imaging scenarios.

The MaxDuplicateImportedComputerSerialNo ComplianceSetting controls the FlexNet inventory agent's behavior in this scenario. Computers with the same serial number on the same connection are grouped into one matched set if the number of computers is less than or equal to the MaxDuplicateImportedComputerSerialNo, which has a default value of two. If the number of computers is greater than MaxDuplicateImportedComputerSerialNo, no grouping will occur, and each computer will remain individually counted (yet still subjected to further assessment by subsequent inventory Matchers).

Update the MaxDuplicateImportedComputerSerialNo setting value to one

While the default setting for the MaxDuplicateImportedComputerSerialNo is two, you can change it by updating the value for this setting in dbo.ComplianceTenantSetting table in the compliance database. Changing the MaxDuplicateImportedComputerSerialNo value to one will prevent any two devices with matching serial numbers from being grouped, essentially disabling the feature.

For FlexNet Manager Suite versions prior to 2020 R1

• To determine the current setting:

SELECT * from ComplianceSetting WHERE settingname LIKE 'MaxDuplicateImportedComputerSerialNo'

If still set to the default, this should return SettingValue=2.

• To change the setting value to one:

UPDATE compliancesetting SET SettingValue = 1 WHERE settingname LIKE 'MaxDuplicateImportedComputerSerialNo'

This will change the value to one and prevent the older device with a matching serial number from being marked as a duplicate.

For FlexNet Manager Suite versions 2020 R1 and newer

• To determine the current setting:

SELECT * FROM SettingName WHERE Name = 'MaxDuplicateImportedComputerSerialNo' -- should return SettingNameID=97

SELECT * FROM ComplianceTenantSetting WHERE SettingNameID = 97

If still set to the default, this should return SettingValue=2.

• To change the setting value to one:

UPDATE ComplianceTenantSetting SET SettingValue = 1 WHERE SettingNameID = 97

This will change the value to one and prevent the older device with a matching serial number from being marked as a duplicate.
