We customized CRM 2011 system. We used some system entities and created some custom entities.
To create custom attributes in system entities, we modified customization XML, added new attributes directly in customization XML and imported that XML
but when we modified XML for one system entity (incident / case), at that time we made one mistake, we added new_name attribute and its primary UI attribute.
For case, now there are two primary UI attributes, we are trying to remove new_name attribute, but CRM throwing error
"Cannot delete Primary UI Attribute: new_name from Entity: Incident"
how can I remove this attribute from CRM system, also we noticed that when trying to filter out custom attributes in solution UI, CRM is not showing custom attributes in this view
