Recently we configured products from CRM to e-commerce setting of The Portal Connector and found that the price for the product was missing.
The way to fix this issue is to Open the product form in CRM and add the list price field on the product form and specify the value there.
Once value is specified, go to administration – portal connector configuration and click on Resynchronize to update the product record in the portal.
Once synchronization is done, we can see the values updated in the portal.
Hope it helps..
