• Feature Configurations: Using the 10 previous orders have been placed for an item calculate the MIN MAX using the SD equation.  Item: Chicken, Filet Spicy PC . The Item Name and VendorCode displayed on the Order will be CHICKEN, SPICY FILETS BRK (101564). The previous 10 orders currently in development are these QTY's - 32,26,22,107,10,5,3,500,4,3 . My calculations for MIN and MAX are -221 and 364 respectively. 

Expected Result

When I click the Inv. & Order Setup menu option in mobile and then select the Item Maintenance menu the Item Maintenance page displays. In the top left Search Items box enter Chicken, Filet Spicy PC.  Highlight the row and then click the details panel accordian for Recommended Min/Max.  What is the requirement for a MIN when the calculation is a NEGATIVE number? I think it should automatically set the value to 1. 

Actual Result

When I click the Inv. & Order Setup menu option in mobile and then select the Item Maintenance menu the Item Maintenance page displays. In the top left Search Items box enter Chicken, Filet Spicy PC.  Highlight the row and then click the details panel accordian for Recommended Min/Max. Minimum is displayed as N/A.
