Why am I getting the message “The price level/U of M combination is not included in the price list for this item.” after setting up a new contract?

This message appears when the U of M or Price Level being used in the Omni Price Check window or Sales Transaction Entry window has not been setup for the specific item being used in the GP Item Price List Maintenance window. Recommendations: Compare the U of M and the Price Levels being used in either the Omni Price Check window or the SOP Transaction Entry window to what has been setup in Great Plains.
