at Microsoft.Crm.ObjectModel.CalculateBaseMoney.ProcessCalculatedColumns(DynamicEntity entity, BusinessEntity entityPreImage, EntityMetadata entityMetadata, String exchangeRateFieldName, Boolean isCreateOperation, ArrayList unchangedAttributes)
Resolution
This problem occurs because a money attribute is created for the entity. When you do this, Microsoft Dynamics CRM 4.0 creates an exchangerate attribute to work together with the money attribute. The money attribute is published as part of the entity. However, if you delete the money attribute, the exchangerate attribute is not removed. Therefore, when you try to run a Microsoft Dynamics CRM plug-in, the plug-in can find the exchangerate attribute. However, the plug-in cannot find the money attribute.
