create a calculated field for the resolution KPI:

sarah knows that she does not make money at her restaurant and is sad if the gross margin percentage falls below 11%; any percentages lower than 11% are Low margin.

sarah knows she makes good money when gross margin percentages exceed 13%; her subdued term for these percentages is High margin.

If gross margin percentages are between 11% and 13% (inclusive) sarah makes the regular amount of money and is neither happy nor sad, and calls percentages in this range Std margin.

After much deliberation, sarah determined the KPI symbols for each range of gross margin % as

: High margin

Std margin

Low margin
