Storing SC attachments in multiple Archiving Systems

Hello All,

We are having a requirement for storing the attachments in two different archiving systems based on the selection of Company Code while Shopping Cart (SC) creation.

EX:

If SC is order for Company Code 1 --> Attachment should be stored in external system 1

If SC is order for Company Code 2 --> Attachment should be stored in external system 2 

Can someone pls provide some input that may be helpful.

Thanks,

Alok
