Calculation result type (attribute/measure)

Content

Hi,

Is there any way to specify calculation result type to be an attribute or a measure?

Thanks,

Alexandr

It should, as in OBIEE depend on the following:

- If column formula contains only attributes then it's attribute

- If column formula contains a measure then it's a measure

I've tried the two formulas you suggested with the samplefile that is included in DVD, the formula was the following

case when Sum(XSA('weblogic'.'Sample Order Lines')."Columns"."# of Orders" by XSA('weblogic'.'Sample Order Lines')."Columns"."City" ) < 50 then 'A' else 'B' end

In this case the new column was shown as Attribute (maybe because of the two alphabetical values) but wasn't acting as attribute in the Chart until I included the City in the chart itself.

case when Sum(XSA('weblogic'.'Sample Order Lines')."Columns"."# of Orders" by XSA('weblogic'.'Sample Order Lines')."Columns"."City" ) < 50 then 1 else 0 end

In this case the new column was shown as Measure (maybe because of the two numerical values) but wasn't acting as measure in the Chart until I included the City in the chart itself.

I believe that due to the mixture of measures and attributes in the formula, you should use the data flow option.

Thanks for the answers!

Example 1:

Add to My Calculations "case when N>100 then 'A' else 'B' end". I`d like to use this as attribute in charts, as X-axis.

Example 2:

Add to My Calculations "case when N>100 then 1 else 0 end". I`d like to use this as measure in charts, as Y-axis.

I know I can add this calculations to data flow or even to SQL.

The question is what My Calculations result type depends on?

A Zmanovskiy

This is correct for data sources and data flow results.

I`d like to do the same for My Calculations results.

There is no way to force it being attribute vs metrics in the front-end.

Maybe you need to use data-flow component to add it to your dataset appropriately.

What is the measure/attribute that you are having problems with? if you describe it better we could help more efficiently

FTisiot

Yes,

If you are just uploading a spreadsheet you can change the attribute/measure definition by editing the data source.

If you use Data Flow, then you must include an aggregation step where you can define measure and attributes.

Thanks for the tip on a calculation containing a measure becomes a measure.

I needed this because I want to subtract two datetimes to get the number of hours between.  The only problem is that it became an attribute and I need it to be a measure.

So, here's my formula:

("End Date & Time Date"-"Start Date & Time Date")*1440+("Headcount"*0)   [extra sources removed for clarity]

Kind of sad that I have to add Headcount*0, but that's how I solved it.  Oracle, we need the ability to control whether it's a measure or an attribute, or you have to somehow be smarter.  Subtracting two times almost always should result in a measure.

Maybe sometimes it needs to be an attribute ... like subtract 1 week from <Event Date> which is date datatype and present as attribute.

Then the resulting column "Event Date LW" can also be used as an attribute.

That said, most of the time, date fields used in calculation formulae result in measures, not attributes <shipment delivery delay in hours/days>.

This may not be the exact question, but relates to the thread : there is a function you can use to turn a metric into an attribute in DF : Attribute(). See this blog+video giving some backrgound with it :https://twitter.com/philippe_lions/status/765933698663510016
