Hi All, I tried to create a PS based monitor using Silect MP Author. and then imported in SCOM. After that, I am not able to modify any monitors in the newly updated MP. Getting below message. Any advise would be highly appreciated. ......................... Note:  The following information was gathered when the operation was attempted.  The information may appear cryptic but provides context for the error.  The application will continue to run. : Database error. MPInfra_p_ManagementPackInstall failed with exception:
Cannot find ManagementPackElement [Type=ManagementPackUnitMonitorType, ID=b99714bc-6401-e8a6-34ee-e0d2a8ee8c56] in management pack [ xxxxx] or any of its referenced management packs.

Hi,

Try to clean the reference manually. Look at this post:
