PIR net price not follow the condition screen

Hi all,

I have a question regarding my pricing condition maintained in a PIR.

In one of my PIR record, there is two validity line records in the pricing condition with the following date range and value:

1 - 2008.04.01 to 2010.12.31 ==> PB00 is USD853,00/1 PC

2 - 2011.01.01 to 2999.12.31 ==> PB00 is USD853,00/1 PC

However, the strange thing is that in the Purchasing Org screen in the PIR, the NET price value is "879,00 per 1pc" even with the VALID-TO field value as "2999.12.31".

May I know why the the Net price in this view not picking up the USD853? Something go wrong in the PIR?

(in between the Pr Date Category is 2-delivery date).

Please help.
