STO creation from the sales order exit
I have a business requirement where I need to create a Inter Stock Transport Order (STO) for a particular kind of sales order. I
I searched and found BAPI(PO_CREATE) to create STO from the sales order exit 'USEREXIT_SAVE_DOCUMENT'.
I am looking to have a single STO from multiple SO (having same concern parties) . Is it possible to achieve this through above BAPI.
If anyone has already developed this ,Please share your thought and Way to achieve this functionality
