# Data Functions in Bex Query Designer

Hi All,

I have made an attempt to explain some of the data functions which can be used as operands when we define formula or Calculated Key Figure

1) COUNT(<Expression>)

This data function is used when we would like to display value of the count made and it returns value 1 if the <expression> is <> 0, otherwise it would return

value as 0

Eg: To display Count of Open Sales orders.

2) DATE

The value is seen as the number of days from 01.01.0000 onwards and is output as a date.

The value can be between 0 and one million, which results in a date between 01.01.0000 and 27.11.2738.

3) NDIV(<Expression>)

It is used when we do some calculations based on division taking into account numerator and denominator. This function returns value 0 if the expression causes a division by 0, otherwise the result is the value of the expression. This is used to avoid error messages or so that we can continue to calculate with a defined result.

E.g: NDIV{5/(2-2)} would result value as 0.

4) NOERR(<Expression>)

Returns 0 if the calculation of <expression> leads to an arithmetical error. Otherwise the result is the value of the expression. Used to avoid error messages  or so that you can continue to calculate with a defined result.

E.g: NOERR(sqrt(-1)) = 0

5) SUMCT <Operand>

Returns the result of the operand to all rows or columns

Example table for operator SUMCT <Operand>

 Year Region Sales SUMCT “Sales” 1999 North 30 60 South 30 60 Result for 1999 60 180 2000 North 60 120 South 60 120 Result for 2000 120 180 Overall Result 180 180

6) SUMGT <Operand>

Returns the overall result of the operand

Example table for operator SUMGT <Operand>

 Year Region Sales SUMGT “Sales” 1999 North 30 180 South 30 180 Result for 1999 60 180 2000 North 60 180 South 60 180 Result for 2000 120 180 Overall Result 180 180

7) TIME

The TIME operator takes any key figure or (partial) formula and makes a key figure of type TIME

For example, the formula is then TIME(Sales).

The system cuts off the decimal places, interprets the value as seconds, and displays the value in format +-hh:mm:ss. For example, 4812 is displayed as 1:20:12
