When searching for IMM material using Attribute option, it causes TC server crash with NXOpen.NXException: An internal Error occurred in the Teamcenter SOA client
Remove all values from the preference IMM_CAD_MATERIAL_VIEW_COLUMN_CONFIG.
This is caused mostly by the attribute owning_user in later TC, there is like a write access check.
This is fixed in IMM 13.3.02.
