Bibliolgraphical record

[Ashok]

Dear Team,
Yesterday I entered a title (bibliographical data) in multiple copies (accession no.) say 1 to 15. Unfortunately the title was entered wrongly in the database. Then I deleted all the data (accession no.) from the record but when I searched the same in the OPAC then I found the data is still persist.

Suggest me how to remove the data permanently?
