Update sales orders status after changing item completion rule

Hello!

I've just changed the item completion rule of a given sales document item (from 'B' to blank). But we have several old orders, which have deliveries created with reference, with some fields still open (due to the 'no reference' status at the item level). The orders created after the new condiguration are ok.

So, is there any way I can update the status of those old orders? Already tried the report SDVBUK00, but did not work out.

Any ideas are welcome.

Thanks.
