allocation for STO orders

Hi Experts,

Product allocation should trigger to STO orders as well. I need to check the product allocation when customer raise the STO orders.

Types of STOs

1-Intra Company - Plant to Plant stock transfer

2-Inter Company - one company code plant to another company code plant in the same company code.

At present allocations are happening only for Sales Orders. I maintained the CVCs, allocation qty in PB, The CVCs and QTYs I have transferred  to Product allocation group. Both sides are in synchronized.

I want to know How I can map the CVCs for STO.

Below characteristics I maintained in product allocation group and POS.

What else i need to maintain in Product allocation group. What characteristics and how i need to create the CVCs for STO orders.

Thanks,
