Release procedure for new company

Hi gurus,

Release procedure for PO is already maintained for my client. Based on characterestics Purchasing organisation, plant, purcasing group and total net order value. Release group is assigned to a class which are all assigned to the above said charactersetics. Now release procedure have to be set for another company having different currency.

System doen not allow me to post a new class to a new release group. So, i additionaly added one more characterisitivs for Net order value in USD and added to the exisiting class. But now release procedure is not working for the exisiting company too.

So what I have to do, to set a release procedure for new company having different currency.

Regards,

RP.
