Windows OS - Desktops Pattern is not inserting specified serial numberIssue <!-- div.margin { padding: 10px 40px 40px 30px; } table.tocTable { border: 1px solid; border-color: #e0e0e0; background-color: #fff; } .title { color: #d1232b; font-weight: normal; font-size: 28px; } h1 { color: #d1232b; font-weight: normal; font-size: 21px; margin-bottom: 5px; border-bottom-width: 2px; border-bottom-style: solid; border-bottom-color: #cccccc; } h2 { color: #646464; font-weight: bold; font-size: 18px; } h3 { color: #000000; font-weight: bold; font-size: 16px; } h4 { color: #666666; font-weight: bold; font-size: 15px; } h5 { color: #000000; font-weight: bold; font-size: 13px; } h6 { color: #000000; font-weight: bold; font-size:14px; } ul, ol { margin-left: 0; list-style-position: outside; } --> When you customize the Pattern Windows OS - Desktops to choose a specific serial number to add to the cmdb for the CI in Discovery, it does not work. It always inserts the first serial number that is found. (This is Step 5 of the Pattern: Insert Serial Number to cmdb_ci_computer - the value field in this step specifies an array element number-$cmdb_serial_number[1].serial_number. Changing it to element 2 does not work.) ReleaseKingston/London/MadridCauseThe Pre/Post Processor Script for the Windows OS - Desktops Pattern contains a line of code that overrides the settings in the pattern and will always write element[1] of the array of serial numbers to the cmdb CI item that is discoveredResolutionNavigate to the Pre/Post Processor Script for the Windows OS - Desktops Pattern: https://<instance_name>.service-now.com/nav_to.do?uri=sa_pattern_prepost_script.do?sys_id=5c2729a40f2f920051a9fa6ce1050e55 Note - In some newer versions, you will need to go to the pre script 'OSs - Pre Sensor' instead Comment out Line 198 where it reads "handleWindowsHardwareInformation();" The line number might be slightly different, depending on version and patch of the instance. It can also appear as handleHardwareInformation(mainCis[ciKey].lookup) in newer versions, in the 'OSs - Pre Sensor' pre script. Modify the array element described in the "Symptoms" section of this article to match the serial number you desire to associate with the CI. *You can always look in the payload of the Pattern to determine which array element your desired serial number is.Save and publish the pattern and do a cache.do to make sure the changes take effect.Run the Discovery
