Sales order stock should post in unrestrcited use stock

Hi

We have MTO and MTS both scenario. Now, for SFG materials we produce through CIR in MD81. Hence, the planned order -> process orders are generated after MRP run has reference of sales order.

Our all SFG products are Auto Goods receipt through COR6N T-code. But, our scenario is for these CIR requirement all process orders stock goes to sales order stock. We can't use these sales order stocks in MTS or, other MTO FGs.

Hence, we want whenever process order confirmation we execute in COR6N, the stock should not be posted through 101E and later we are doing 411E. Rather we want in COR6N the stock should go to unrestricted use stock.

What are all config settings or, processes are there to satisfy our requirement. Also, what can be negative impact for that.

Please suggest.

Thanks,

Susanta
