GR for a non valuated sales order

Dear Friends,

We are using non valuated sales order production for a particular scenario and assigned  requirement class 040 in the sales order.

No FI document is created for mtype 261 for goods issue to production order and goods receipt 101E which is fine.

When we do stock transfer from sales order stock to unrestricted using 411 E system(against the same sales order)  a FI document ( Inv Dr/ COGm CR) is posted.

I was expecting no FI document for 411 E until RA is done against sales order, could you please let me know if I am  missing something?

Thanks,
