Folks,

I am trying to create what seems to be a pretty simple calculated member, which will go back (from my current date) and find the previous date with any data entered (some of the dates have no info entered).  I am using recursion as follows:

``````with
member [Date].[Calendar].[BeforeCurrentWithData] as
iif(
([Date].[Calendar].currentmember.prevmember, [Measures].[Sales]) <> 0,
[Date].[Calendar].currentmember.prevmember,
[Date].[Calendar].[BeforeCurrentWithData]
)
select
{[Date].[Calendar].[BeforeCurrentWithData]} on columns,
[Date].[Calendar2].[Date].members on rows
from [MyCube]
;
``````

Hi

The way I would do that. I would identify current date (I use VBA MDX functions) and filter for non empty based on measure group and take the first one using tail function.

There might be a better way of doing that. Maybe some last non empty but I'm sure.

Hope that gives you more options to experiment with
Regards
Emil

You can use LAG or PARRALLEL PERIOD  take your pick.

See below for a example, I use both Lag and ParallelPeriod:
``````CREATE MEMBER CURRENTCUBE.[MEASURES].[Closed Relationship - STLY (Complete)]
AS SUM(
FILTER
(EXISTING([Geography].[Agency].[Agency]),
[Geography].[Import Start Date].CURRENTMEMBER.MEMBERVALUE <=
HEAD(EXISTING [Date].[Date].[Date]).ITEM(0).ITEM(0).LAG(365).MEMBERVALUE
),
Aggregate(Generate(EXISTING [Date].[Calendar].[Month].Members, {ParallelPeriod([Date].[Calendar].[Year], 1)}), [Measures].[Closed Relationship])
),
FORMAT_STRING = "#,#;(#,#);0;\-",
VISIBLE = 1;
``````
