Example 6-14 Finding Values in an Absolute Range

Suppose you are interested in how close your planned 1996 sales figures for sportswear in Boston were to the actual sales. You would like to see those months where budgeted figures are off by more than $5,000 in either direction. You can use ABS to help you find those months.

LIMIT product TO 'Sportswear'
LIMIT district TO 'Boston'
LIMIT month TO YEAR 'Yr96'
LIMIT month KEEP ABS(sales - sales.plan) GT 5000
REPORT DOWN month sales sales.plan sales - sales.plan

These statements produce the following output.

DISTRICT: BOSTON
