Symptom
You are using Migration/Mass Data Maintenance/Data Workbench to change the Start Date of some Opportunities, after successful change, you have observed that the Negotiated Value for the Products in the Products tab (In Opportunities) is reset to Zero.
Reproducing the Issue
You have exported few Opportunities through Mass Data Maintenance and Imported in again with the changes to the Start Date.
After that, when you check those Opportunities, the Negotiated Value are set to Zero for the Products assigned in those Opportunities.
Cause
The cause for the issue is that when start date is changed, price evaluation changed and gives result as 0. With original start date it works .
There is an additional check that if negotiated value has been overridden by the user to a different value than what is proposed by system , then system do not update it anymore.
In this case, the user did not override system proposed value , hence when start date changed price evaluation applies new value to it.
Resolution
This is expected system behavior.
