Sales Last / Previous Week

[Anonymous]

Hi Guys,

I need an comparisation between Sales current week vs last week. But I need the possibility to select a week so the function above or below doesn't work. Here is my Sales table;

What is the proper set analysis for getting the previous record?

Pls advice

Regards,

Robert

WeekY	Previous Orderportfolio	Current Orderportfolio
2015/37	7.363.248	7.854.268
2015/36	7.038.389	7.363.248
2015/35	7.025.413	7.038.389
2015/34	7.373.356	7.025.413
2015/33	7.319.992	7.373.356
2015/32	6.876.961	7.319.992
2015/31	7.009.264	6.876.961
2015/30	6.666.926	7.009.264

This seems like already aggregated (expected) data, can you share raw data?

Hi Sunny,

Yes, sum of

but it's just what i did in Excel. Now i need a set analysis to reproduce the same data.

Can you use this as sample data?

Do you have two columns in your database for Current and Previous period? or is it just one column and this is a kind of display you want to create?

Set analysis will not help in a row-by-row expression such as previous week. A set expression is evaluated once for the table and not on a row by row basis.

Have a look at Above() or Below() chart functions if you want to do this in a table.

For example, a straight table

• Dimension: WeekY
• Expression1: your existing expression for current portfolio
• Expression2: =Below(Column(1))    for previous portfolio

Yes, correct.

It's just one column (Sales) with the value. Previous is the calculation i need.

Hi Jonathan,

Thanks for reply.

If i use the functions,I cannot select a certain week (like wk 2015/35), because this will show me zero for previous. column. Logic because I do not have a below or above records...

Try

t1:

load * Inline

[

WeekY,Current Orderportfolio

2015/37,7.854.268

2015/36,7.363.248

2015/35,7.038.389

2015/34,7.025.413

2015/33,7.373.356

2015/32,7.319.992

2015/31,6.876.961

2015/30,7.009.264

];

NoConcatenate

t2:

LOAD

WeekY,[Current Orderportfolio],if (isnull(Peek([Current Orderportfolio])),0,Peek([Current Orderportfolio])) as [Previous Orderportfolio]

Resident t1 order by WeekY;

drop Table t1;

May be this:

Script:

Table:

LOAD *,

  Rand() * 100000 as Value;

LOAD Year(Today() - RecNo()) & '/' & Week(Today()-RecNo()) as YearWeek,

  Date(Today() - RecNo()) as Date,

  Year(Today() - RecNo()) as Year

AutoGenerate 618;

How it looks in Table Box:

Straight Table:

Dimension: YearWeek

Expressions

1) 2015: =Sum({<Date = {"$(='>=' & Date(YearStart(Max(Date))) & '<=' & Date(Max(Date)))"}>}Value)

2) 2014: =If(Sum({<Date = {"$(='>=' & Date(YearStart(Max(Date))) & '<=' & Date(Max(Date)))"}>}Value) > 0, Above(Sum({<Date = , YearWeek = >}Value), 52))

I hope this is what you are looking for.

Best,
