Why is my On Hand Quantity Different between the Stock Card and the Master Order screen?

The Stock Card displays 'Beginning' and 'On Hand' quantities for Central Storage only.

The On Hand quantity displayed on the Master Order detail screen at the ship is driven by the following preference:  Setup > Corporate > Preferences > Purchasing tab > 'On-Hand Includes'.  The choices are 'Central', 'Customer', 'Both'.

On Hand Includes — For cruise ship master orders, this preference allows the company to indicate which storage location(s) should be included when determining the current ‘On Hand’ quantity for use in the Suggested Order calculation. The choices are 'Central', 'Customer', or 'Both'

 If preference is set to 'Central', then the numbers should match.  If it is set to anything else, they may differ.
