Creation of Sales Order throogh Intercompany STO

Dear SAP Gurus,

I have a question

In the intercompany stock trasnport orders.As per the standard process

i) Creation of STO

ii) Creation of replenishment delievry.

iii) Goods Issue from the supplying plant.

iV) Good receipt at the receiving plant.

Our requirement is to create a sales order through IDOC in place of delivery at the delivering company code.

All the subsequent docuements like delivery and shipment will be based on this newly created sales order.

I want to know primarily that is there anyway of creating a sales order instead of Delievery subsequent to creation of STO.

IF so how can we disable the SAP standrad process ( Std Intercompany STO process) and enable our requirement.

A quick response is highly appreciated.

Regards

Ganesh
