Diagnosis
The system makes the target unit of measure equal to the sales unit ofmeasure.

System Response
Target and sales unit of measure for the item deviate from one another,and at least one of the two is a proportion or product unit of measure.This means that the item status cannot always be correctly determinedand the system treats the units of measure as the same.

Procedure
Because the target unit of measure has changed, check the targetquantity. You can only change the target unit of measure if the salesunit is neither a proportion of production unit of measure.
