Convert using values from another table

[system]

Hi

I use BO 6.5

I have a table with columns: weight and meassure

weight beeing the value and meassure what kind of unit.

Ex:
150 pound
45 kg
4325 g

I have another table that have: From_Unit, To_Unit, and Multi_factor

Ex:
LBS KG 0,453592

So if I have in my first table 5 LBS
I have to mutliply this by 0,453592 to get kg.

In my report I want all my values to be in kg.
I was hoping that something like this would help:

=<Multi_factor> where (<From_Unit> = )

If I hardcode “LBS” instead of it works fine.

Thank you in advance.

The syntax of the Reporter WHERE clause does not support it. Can’t do it.

See this entry from our Reporter FAQ: Why do I get a Syntax Error (DMB0007) when I try to Sum() Where ( > 2000)?

The syntax has to be WHERE <variable/object> = constant.

The FAQ cited above suggests a work-around for one situation, perhaps you can figure out another for your case.

Alternatively, couldn’t you get the universe designed so that there’s an automatic join on the from_unit, so that you can pull in the correct to_unit and multi_factor objects?

Or to get around it in the report itself, link measure object from first query with from_unit (2nd query)
Then create a combined_measure variable as

= If <measure>="pound" Then "LBS" Else <measure> 

Apply break on combined_measure and use the below expression on the block footer to get value in kgs

= If <combined_measre>="LBS" Then <Multi_factor>*<Weight> Else <Weight> 

Show other column values on the footer and do a fold from format-breaks.

This is based only on the LBS/pound conversion to kgs.
