How to search a value inside a table

[#1]

Hi,

I have the following two tables:

qualify *;

unqualify Article;

MEDIUMCOST:

load * inline

[

Article, Year, Cost

123, 2009, 100

123, 2008, 120

456, 2007, 68

456, 2006, 50

];

SALES:

load * inline

[

Article, Year, Price

123, 2009, 500

123, 2008, 240

456, 2009, 90

456, 2007, 60

456, 2005, 30

]

;

Now I have to calculate the cost and i can have the following cases:

- I have sold a product in one year and i have the evaluation of the cost for this year (product 123 sold in 2009 the cost for the year 2009 is 100)

In this case i should see the cost of the year that match, so 100

- i have sold a product in one year and i have the value of the cost in one of the previous year (product 456 sold in 2009 the cost are available only in 2007 and 2005)

in this case I should see the first cost available in the first year available. In my example the cost of product 456 in Year 2007 = 68

- i have sold a product in one year and i have no value of cost in the previous years (product 456 sold in 2005)

In this case I should have cost = 0

Any suggestion?

Thanks!!

You should have an interval dates for cost value by Product (Article). For example:

load * inline

[

Article, YearStart, YearEnd, Cost

123, 2009, 2099, 100

123, 2008, 2008, 120

456, 2007, 2099, 68

456, 2006, 2006, 50

];
The field "YearEnd" you may calculate from your field "Year".

then after you will get such table you should use intervalmatch() function.(see more details in help)

sparur has sent you on the right track but I've attached an example because there are a number of steps.
