How can I have PowerShell talk to SAM and CMDB

     I have a powershell script that talks to SAM at the backend, which then talks to CMDB. PS calls SAM.exe then "Unmanage" a CI from CMDB.

      # Unamanage CI in CMDB

      c:\SAM\SAM.exe /BATCH /h $PCName /f UNMANAGE  /c $ChangeNumber

     # Remanages CI in CMDB

      c:\SAM\SAM.exe /BATCH /h $PCName /f MANAGE

Is there a way that I can also update a field called "Memory" to "16GB" after it has unmanaged the PCName.

Any help would be grateful.
