Cause: This error occurs when you do not have an EntID setup for your Entity.
Resolution: To resolve this issue follow the steps below:
- Click the Data Entities icon on the AppStudio toolbar.
- Open up the Entity of the screen you are performing the upload on.
- Click Edit Fields.
- You must add an EntID field that matches the name of your primary key. For example, if your primary key name is AgentID than your field must be called EntAgentID.
- Click Edit Mapping and map your EntID field to your primary key.
- Change the mapping direction for the EntID field to include an upwards arrow and the primary to have a downwards arrow.
