Overview:

When a user is opening a Call record in Online CRM, an error appears: A system error has occurred and Veeva Systems has been notified.

Root Cause:

There are one or more Detail Products associated with the Call record or its Child Calls that the user does not have access to.

Solution:

1. Identify the Detail Products associated with the Call by running the following query as a System Administrator:

   SELECT Id,Name,Call2_vod__c,Product_vod__c,Product_vod__r.Name FROM Call2_Detail_vod__c 
   WHERE Call2_vod__c='<SFDC ID of the Call>'

2. Verify the Sharing Settings and grant access to the Detail Products that the user is missing.
3. Clear Veeva Cache.
