ARTCC data controller inadvertently removed the data block on an air carrier aircraft and the error wasn't discovered until the aircraft proceeded into the adjacent ARTCC airspace. No separation was lost and the aircraft was reidented by the adjacent ARTCC.

Narrative:
I was working the radar position at a 'test' sector. Traffic was busier than normal due to a scope failure and I was working 2 sectors. A non control person (flight data) removed the flight on an aircraft under my control. The data block was dropped from my scope along with any flight plan information. After the flight plan information was removed, the aircraft continued from my congested airspace into ZOB's less congested airspace before being detected and re-idented. The flight data position removed the wrong flight plan with a simple enter button with no checks or verifications.

Title: ARTCC DATA CTLR INADVERTENTLY REMOVED THE DATA BLOCK ON AN ACR ACFT AND THE ERROR WASN'T DISCOVERED UNTIL THE ACFT PROCEEDED INTO THE ADJACENT ARTCC AIRSPACE. NO SEPARATION WAS LOST AND THE ACFT WAS REIDENTED BY THE ADJACENT ARTCC.
Narrative: I WAS WORKING THE RADAR POS AT A 'TEST' SECTOR. TFC WAS BUSIER THAN NORMAL DUE TO A SCOPE FAILURE AND I WAS WORKING 2 SECTORS. A NON CTL PERSON (FLT DATA) REMOVED THE FLT ON AN ACFT UNDER MY CTL. THE DATA BLOCK WAS DROPPED FROM MY SCOPE ALONG WITH ANY FLT PLAN INFO. AFTER THE FLT PLAN INFO WAS REMOVED, THE ACFT CONTINUED FROM MY CONGESTED AIRSPACE INTO ZOB'S LESS CONGESTED AIRSPACE BEFORE BEING DETECTED AND RE-IDENTED. THE FLT DATA POS REMOVED THE WRONG FLT PLAN WITH A SIMPLE ENTER BUTTON WITH NO CHKS OR VERIFICATIONS.
