PO Approval Date is lesser than the Order Date

Hello,

I have noticed a strange issue in my system that Approval Release Date (RDJ) is lesser than the Order Date (TRDJ). This was happened when a purchase order tried to release. Is this a standard feature of JDE or was it a bug. when i started explore i found that the PO price effective date (PEFJ) is also showing less than the order date. Here find the example values on the issue.

JDE Version : 9.0

F4311: (Purchase Detail)

Order No: 15000264 OR 00200

Order Date : 11/08/2015

Price Effective Date : 11/04/2015
