Come in to put on record (5)
I believe the answer is:
enter
This clue is a double definition.
'come in' is the first definition.
(synonyms)
'put on record' is the second definition.
(I've seen this in another clue)
'to' acts as a link.
(Other definitions for enter that I've seen before include "Record - stage direction - come in" , "Break in" , "cross the threshold" , "Go in - set down" , "Pierce" .)
