Deactivate horizon period for dynamic credit check

Dear All

At present, system is using dynamic credit check with the below setting.

OVA8:Static check is not ticked & open orders is ticked.

          Dynamic check is ticked & reaction is C and status is ticked and the period is 3 Months.

Now, the requirement is to remove horizon period (to consider all sales orders irrespective of delivery due date) and everything else has to continue with respect to the existing system.

I would like to confirm from you that by (OVA8) deactivating dynamic check and activating static check will solve this requirement?

Or If there is some other way to fulfill this requirement, please do suggest me.

Please help me on this.

Thanks & Regards

Rajesh
