* Missing correlation id (Correlation id)
* Missing parent correlation id in case the type is Control module (Control module parent id)
* Missing serial number (Serial number)
* Missing transformed name (Transformed name)
* Missing MAC Address (validation is executed on column MAC Address 1)
* Missing type (Type)
* Missing rack number (Rack number)
* Missing slot number (Slot number)
* Equipment model entity path does not exist (Equipment model entity path)

* Validate Invalid types - Compare against the default Excel type to OT device type mapping through the sn_otsm_sgc.SGOTAssetImportExtensionPoint extension point implementation.

  If you have additional
  mappings, create an extension point implementation for the base system sn_otsm_sgc.SGOTAssetImportExtensionPoint extension point.
