You can use the following data functions when defining a formula or a calculated key figure as an operator.
NULL values are displayed as empty cells, not as 0. For more information about when NULL values occur, and how they are displayed, see Technical Notes About the Formula Operators.
Value = 1 if operand <> 0, otherwise 0 (numerator)
Returns value 1 if the expression <> identified by <Expression> results in 0, otherwise 0.
Processing a Value as a Date
The value is given as the number of days starting from 01.01.0000 and then displayed as a date.
The value can be between 0 and a million. This which allows for a date range between 01.01.0000 and 27.11.2738.
Value = 1 if operand = 0, otherwise 0
Returns value 1 if the expression identified by <Expression> results in 0, otherwise 0.
This function is identical to the NOT operator and should not be used anymore.
NDIV0 (x): Equals 0 when divided by 0, otherwise x
Results in 0 if the expression identified by <Expression> is caused by a division by 0 during calculation. Otherwise, the result is the value of the expression. This is used in order to avoid error messages or so that you can continue calculating with a defined result.
Values Without Dimensions (Without Units)
Returns purely numerical values of <expression> and suppresses units and currencies.
You can use this function to prevent the system from displaying the "mixed currency" character. See SAP Reference IMG → SAP Customizing Implementation Guide → SAP NetWeaver → SAP NetWeaver Business Warehouse → Settings for Reporting and Analysis → General Settings for Reporting and Analysis → Display of Numeric Values in Business Explorer.
NOERR (x): Equal to 0 for undefined calculations, otherwise x
Results in 0 if the calculation of <expression> causes an arithmetical error. Otherwise, the result is the value of the expression. This is used in order to avoid error messages or so that you can continue calculating with a defined result.
NOERR(SQRT(1)) = 0
Result
Returns the result of the operand to all rows or columns (more information: Percentage Functions% CT).

Query Result
Returns the query result of the operand (more information: Percentage Functions %RT).
Unlike the process for calculating the overall result, dynamic filters are not used in the calculation of the query result. This means that the calculation always normalizes to the same value, irrespective of the filter status and the navigational state.

The year 1999 is in the dynamic filter. The missing sales (120) come from the year 2000 (see SUMGT).
Processing a Value as a Time
The TIME operator takes any key figure or (partial) formula and makes a key figure of type TIME. Go to the formula editor. For the operator, doubleclick the Process Value as Time data function. For the operand, doubleclick the key figure you want. The formula could then be TIME(Sales).
The system removes the decimal places, interprets the value as seconds, and returns the value in the form +hh:mm:ss. 4812 is displayed as 1:20:12 for example.
Any number is seen as the number of seconds from 00:00:00 and is displayed in hours, minutes, and seconds. A key figure of type TIME with value 0 is displayed as 00:00:00.
Negative times are allowed: For a negative number the system calculates backwards from 00:00:00.
You can enter any number of hours. After 24 hours, the system does not restart again at 0.
This function is mainly intended for offset calculations. If you want to calculate 4 hours for time key figures for example, you can use the TIME operator.
