Hi,
check in vl02N , in condition tab ---> click on analysis button whether pricing procedure is picking or not.
If it is picking it is very nice check in vk11 whether any condition records are maintained or not.
If pricing procedure not picking check with your SD consultant , whether they assigned pricing procedure with respect to sales area means with respect to sales ORG and distribution channel and dividision combination.
You can do this directly by going to T-Code OVKK. Give your relevant sales area + Document pricing procedure + Customer pricing procedure and then assign that Pricing procedure...
