MOVINGTOTAL

The MOVINGTOTAL function (abbreviated MVTOT) computes a series of totals for the values of a dimensioned variable or expression over a specified dimension. For each dimension value in status, MOVINGTOTAL computes the total of the data in the range specified, relative to the current dimension value.

When the variable or expression has only the specified dimension, MOVINGTOTAL produces a single series of totals, one for each dimension value in the status. When the variable or expression has dimensions other than the one specified, MOVINGTOTAL produces a separate series of totals for each combination of values in the status list of the other dimensions.

Return Value

DECIMAL when the data type of expression is DECIMAL or SHORT; otherwise, NUMBER.

Syntax

MOVINGTOTAL(expressionstartstopstep, [dimension [STATUS|limit-clause]])

Parameters

expression

A numeric variable or calculation whose values you want to total; for example, UNITS or SALES-EXPENSE.

start
stop

Integer values that specify the range of values over which you want to total. The value of start specifies the beginning of the range. The value of stop specifies the end of the range. Specify the values of start and stop relative to the current value of dimension. To specify a negative position for start or stop preceed the value with a comma. Thus, you specify zero (0) for the current dimension value, and -1 for the value preceding the current value. (See also "How the Moving Functions Handle Out-of-Range and NA Values".)

Note:

By default this function uses the default status list when identifying the range of values to average. You can specify either the STATUS or limit-clause phrase to change this behavior.

Tip:

When you want to range to the end of status, for convience and to document your intent, specify the value of stop as OBJ function with the DIMMAX keyword
step

A positive whole number that specifies whether to total over every value in the range, every other value, every third value, and so on. A value of 1 for step means total over every value. A value of 2 means total over the first value, the third value, the fifth value, and so on. When the current month is Jun96 and the start and stop values are -3 and 3, a step value of 2 means total over Mar96, May96, Jul96, and Sep96.

dimension

The dimension over which the moving total is calculated. While this can be any dimension, it is typically a time dimension.

When expression has a dimension with a type of DAY, WEEK, MONTH, QUARTER, or YEAR and you want MOVINGTOTAL to use that dimension, you can omit the dimension argument.

STATUS

Specifies that MOVINGTOTAL should use the current status list (that is, only the dimension values currently in status in their current status order) when calculating the moving total.

limit-clause

Specifies that MOVINGTOTAL uses the values specified by a LIMIT function or those specified with the same syntax as any of the limit-clause arguments in the various forms of the LIMIT command (that is, the syntax of the LIMIT command after the limit-type argument such as "TO"). For the syntax of these arguments, see LIMIT (using values) command, LIMIT using LEVELREL command, LIMIT (using parent relation), LIMIT (using related dimension) command, LIMIT NOCONVERT command, and LIMIT command (using POSLIST).

Examples

For an example of calculating a moving total sales, see Example 8-31, "Calculating a Moving Average".
