Services for object using cl_gos_manager

Hello All,

I have a selection screen with material no as a parameter. After I execute the screen I get some details for that material. I want to replicate "Services for object" functionality as in ME23N in my Program. I am able to add attachments using cl_gos_manager. But when I add a document to a material I am able to see the attachment with all the materials.

I have created a object using SWO1.

Then I have created an object for the class cl_gos_manager.

How do I make the attachments material specific.

Thanking you all in anticipation.

Regards,

Anju
