Single condition to trigger out of two mandatory conditions without error

Hi Friends,

I have two mandatory conditions as PR00 and PR10. If both the condition records are maintained then both are triggering in sales order but PR00 is inactive and PR10 is active. This is fine.

But if condition record is maintained for only either one, then I am getting error as ' other condition type missing'.

How to resolve this. I cannot remove mandatory because, sometimes by mistake user may not maintain record for both the condition types, where in I will not have any control.

Kindly help me to resolve this.
