how to avoid inserting duplicate file name in sys_attachment table

[Arun91]

Hi Team,

We are using order guide and have created a variable as attachment. We are cascading the variable in servicenow.

Based on no of RITM attachments are inserted to sys_attachment table. Could you please help me how to avoid the duplicates while inserting the attachment into sys_attachment table.
