Lookup Value

[Anonymous]

Hi All,

I am using a LOOKUP Function.

This is the DAX formula I am using.

EDU = LOOKUPVALUE('Workbench Export 20220126180530'[Effective Daily Usage],'Workbench Export 20220126180530'[Part Number],'Part Analysis'[PartNumber])

I am getting an error that says 'A table of multiple values was supplied where a single value was expected'

Can I please know how to correct the above formula?

Any help is appreciated!

Thank you!

@Anonymous If that is a measure, then you will need an aggregation around your last parameter, like MAX, MIN, etc. Also, I have found using something like MAXX(FILTER(...),...) tends to be more reliable than LOOKUPVALUE.

Thank you! @Greg_Deckler 

But it is neither a measure nor a calculated column.

Thank you!

@Anonymous OK, if it isn't a measure or a calculated column then it is a table and it is the same answer for a table as with a measure. Perhaps you could explain what you are trying to accomplish with sample data and this will go faster.

Sorry, having trouble following, can you post sample data as text and expected output?

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

@Greg_Deckler , I have 2 tables and I have Effective Daily Usage in Table2.

Table-1

PartNumber

35275913X

35275894X

35087611

13925560

35264448X

35087603X

Table 2

Part Number	Effective Daily Usage
13815957X	1105.73214
9402709	128.55357
12092075	220.26786
16243058	4140.39286
13862570X	26.78571
15514195X	138.44643

I am trying to Lookup Effective Daily Usage from the table 2 to table 1 for further calculation in that table.

Thank you!

@Anonymous Well, the formulas would be:

Column in Table-1 = MAXX(FILTER('Table 2','Table 2'[Part Number] = 'Table-1'[PartNumber]),[Effective Daily Usage])

Column in Table-1 Lookup = LOOKUPVALUE('Table 2'[Effective Daily Usage],'Table 2'[Part Number], 'Table-1'[PartNumber])

Measure = MAXX(FILTER('Table 2','Table 2'[Part Number] = MAX('Table-1'[PartNumber])),[Effective Daily Usage])

Measure Lookup = LOOKUPVALUE('Table 2'[Effective Daily Usage],'Table 2'[Part Number], MAX('Table-1'[PartNumber]))
