The function returns the nth previous cell member from mbrName, in the sequence XrangeList, with options to skip #MISSING, zero, or both #MISSING and zero values. All other dimensions assume the same members as the current member. @PRIORS works only within the designated range.

Syntax

@PRIORS(SKIPNONE | SKIPMISSING | SKIPZERO | SKIPBOTH mbrName[,n, XrangeList])

Parameters

SKIPNONE

Includes all cells specified in the sequence, regardless of their content.

SKIPMISSING

Ignores all #MISSING values in the sequence.

SKIPZERO

Ignores all zero values in the sequence.

SKIPBOTH

Ignores all #MISSING and zero values in the sequence.

mbrName

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

n

Optional signed integer. Using a negative value for n has the same effect as using the matching positive value in the @NEXTS 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 set 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 Time dimension.

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.

Example

In this example, Prev Inventory for each month is derived by taking the Inventory value from the previous month and ignoring #MISSING and zero values. Because n is not specified, the default is 1, which provides the next prior member in the range. Also, because XrangeList is not specified, the level 0 members from the dimension are set as Time used as (Jan,Feb,Mar,...).

"Prev Inventory" = @PRIORS(SKIPBOTH,Inventory);

The following report illustrates this example:

                  Jan      Feb      Mar     Apr     May    Jun
                  ===      ===      ===     ===     ===    === 
 Inventory       1100     #MI     1000     1300      0    1400
 Prev Inventory   #MI    1100     1100     1000   1300    1300            

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

FIX(East)
"Prev Sales" = @PRIORS(SKIPBOTH,Sales, 1, @XRANGE("2011"->"Sep", "2012"->"Mar"));
ENDFIX;

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
