How is SC & PO Linked in database.

Hi All,

We create the Shopping Cart and then using SC no we create the Purchase Order PO No.

I want to know from the PO No how can I get SC No.

I can have seen lot of function modules but no one gives us that.

If anybody have any idea on this please let me know.

If any tables are linked at the backend please let me know.

Thanks & Regards,

Pankaj Dwivedi
