Planned standard cost changes.

This is giving us wrong reports and it is business critical issue.

1. What is your problem or concern?

The planned Standard cost keeps changing, it is incorrect, I am trying to correct it but it does not stay correct, I update the price on the planned standard cost record but it goes back to the incorrect price after certain time, and when I run the revalue inventory, it picks up the incorrect pricing.

2. What are the exact steps to reproduce your problem (Indicate if Production or Sandbox)?

Production - it only does it for few items, so not exactly sure if its producible but when I change the price of the components on planned standard cost record and re run the cost roll up and revalue standard cost inventory at some point it goes back to the incorrect value.
