The TOTAL qualifier is added to aggregation functions to disregard chart dimensions and make the calculation over the entire record set as defined by the current selection state.
In a previous section, we calculated the percentage of FTEs each carrier performs relative to the total number of FTEs and we used a variable (vTotalFTEs) to store the divisor value. Instead of using a variable, the same calculation can be made using the following expression:
Sum([# Equivalent FTEs]) / Sum(TOTAL [# Equivalent FTEs])
When the preceding expression is used in a straight table with Carrier Name as the dimension, the numerator will calculate the value corresponding to each carrier, which will be different on each row of the table. The divisor will calculate the total number of flights made by all carriers, which will be the same for all rows of the table, therefore disregarding the dimension value.
Additional modifiers can be used along with the TOTAL qualifier to disregard only...
