Symptoms

After uploading a PPR file, resource rate period prices were changed to zero for some plans. 

Cause

Software related issue #PDI-1558 - 'PlanRatePeriod existing fields are voided during update' 

Due to that issue when PlanRatePeriods are updated by means of PPR, PLM voids multiple fields like recurringFee, RecurringSKU and others (mostly fees and SKUs).

As a result, prices are no longer shown in UX1 Marketplace. 

The issue has been fixed in PLM-1.6.348.

Resolution

Schedule PLM upgrade with your TAM. 

Workaround

At the moment, the only way to restore prices now is to upload the correct prices via product inventory.
