@PRIOR

Returns the nth previous cell member from mbrName, in the sequence XrangeList. All other dimensions assume the same members as the current member. @PRIOR works only within the designated range, and with level 0 members.

Syntax

@PRIOR (mbrName [, n, XrangeList])

Parameter	Description
mbrName	Any valid single member name or member combination, or a function that returns a single member or member combination.
n	Optional signed integer. Using a negative value for n has the same effect as using the matching positive value in the @NEXT function. If you do not specify n, then a default value of 1 is assumed, which returns the next prior member from the lowest level of the dimension tagged as Time in the database outline.
XrangeList	Optional parameter specifying a sequential range of members. If a range is not specified, Essbase uses the level 0 members from the dimension tagged as Time. Can be a valid member name, a comma-delimited list of member names, cross dimensional members, or a return value from a member set function or range function (including @XRANGE). For more information about rangeList and XrangeList, see Range List Parameters in the topic Range and Financial Functions.

Parameter

Description

mbrName

Any valid single member name or member combination, or a function that returns a single member or member combination.

Optional signed integer. Using a negative value for n has the same effect as using the matching positive value in the @NEXT function. If you do not specify n, then a default value of 1 is assumed, which returns the next prior member from the lowest level of the dimension tagged as Time in the database outline.

XrangeList

Optional parameter specifying a sequential range of members. If a range is not specified, Essbase uses the level 0 members from the dimension tagged as Time.

Can be a valid member name, a comma-delimited list of member names, cross dimensional members, or a return value from a member set function or range function (including @XRANGE).

Example

In this example, Prev Inventory for each month is derived by taking the Inventory value from the previous month. Since n is not specified, the default is 1, which provides the next prior member in the range. Since XrangeList is not specified, the level 0 members from the dimension tagged as Time are used (Jan,Feb,Mar,...).

"Prev Inventory" = @PRIOR(Inventory);

This example produces the following report:

                Jan     Feb     Mar     Apr    May    Jun
                ===     ===     ===     ===    ===    ===                       
Inventory      1100    1200    1000    1300   1300   1400
Prev Inventory  #MI    1100    1200    1000   1300   1300

The following example assumes a Year dimension is added to Sample Basic.

"Prev Sales" = @PRIOR(Sales, 2, @XRANGE("2011"->"Sep", "2012"->"Mar"));

The above calculation is performed across the following multidimensional range specified by XrangeList:

2011->Sep
2011->Oct
2011->Nov
2011->Dec
2012->Jan
2012->Feb
2012->Mar
