Shopping Cart Attachment via FM BBP_PD_SC_CREATE

Hi,

I am trying to create Shopping cart with attachment using RFC enable function module BBP_PD_SC_CREATE. This FM has a parameter IT_ATTACH to pass the attachments. I would like to know how to pass values to this parameter and what are the values to be passed to the different fields of the structure other than the file content.

Please help if anybody has done so.

Thanks
