GOS - check for duplicate Attachments

Hi guys!

Fianlly i managed it to add a URL to GOS in my abap program

i used the following FMs

CALL FUNCTION 'SO_FOLDER_ROOT_ID_GET'

CALL FUNCTION 'SO_OBJECT_INSERT'

CALL FUNCTION 'BINARY_RELATION_CREATE'

So what i do is running an abap report in a batch job which adds me the necessary urls.

Now i need to now how i can check for duplicates in the gos. In particular check if this link is already there or not?

who knows?

thanks!!
