QlikView Join; What I'm doing wrong? - join

Question

I want to join two tables, and insert the new calculate data on the first one, look at the example:
Table1:
Measure Value Date
Units 1.00 1
Dollar 25.00 1
Units 1.00 2
Dollar 25.00 2
Table2:
Date Rate
1 1.05
2 1.09
I would like to include on the Table 1, this lines that means (Dollar: Value * Rate on the same Date)
Measure Value Date
LocalValue 26,25 1
LocalValue 27,25 2
I'm try to do like this, but I continue have a problem:
JOIN (Table2)
LOAD
'LocalValue' as [Measure],
[Value]*[Rate] AS [Value]
RESIDENT Table1
WHERE [Measure] = 'Dollar'
but I'm geting this error message:
Error Field not found -
What I'm doing wrong?
Example here:
Table1:
Load * inline
[
Measure,Value,Date
Units,1,1
Dollar,25,1
Units,1,2
Dollar,25,2
];
Table2:
Load * inline
[
Date,Rate
1,2
2,3
];
Table1:
JOIN (Table2)
LOAD
'LocalValue' as [Measure],
[Value]*[Rate] AS [Value]
RESIDENT Table1
WHERE [Measure] = 'Dollar'

Answer 1

At the point when you try "join (Table2) " fields Rate and Value do not exists in the same table from which you are trying to load (Table1).
You need to have fields Value and Rate in one table before join the LocalValue calculation.
Your script need to look like this:
Table1:
Load * inline
[
Measure,Value,Date
Units,1,1
Dollar,25,1
Units,1,2
Dollar,25,2
];
join
Table2:
Load * inline [
Date,Rate
1,2
2,3
];
JOIN (Table1)
//Table1:
LOAD
'LocalValue' as [Measure],
[Value]*[Rate] AS [Value]
RESIDENT Table1
WHERE [Measure] = 'Dollar'
And the result table will be:
Measure Value Date Rate
Dollar 25 1 2
Units 1 1 2
Dollar 25 2 3
Units 1 2 3
LocalValue 50 - -
LocalValue 75 - -
