If statement returning results from separate table

[Anonymous]

Hi All,
I have two tables Faults_IEC and Faults_GADS both have a category column and unique IDS for each category. I'm trying to build a measure that can be used in a graph to show 

if IEC category = "Forced Outage*" then return Gads category if not return IEC category.

I initial thought to merge the two tables in Power Query however the Unique ID's overlap.

Ideally, I would want to be able to use it in a bar chart like below

Hi @Anonymous ,

You can create a calculated column as below in the table Faults_IEC, later check if it is working OK in your side.

Column =
IF (
    'Faults_IEC'[IEC category] = "Forced Outage*",
    CALCULATE (
        MAX ( 'Faults_GADS'[Gads category] ),
        FILTER ( 'Faults_GADS', 'Faults_GADS'[ID] = 'Faults_IEC'[ID] )
    ),
    'Faults_IEC'[IEC category]
)

If the above one can't help you figure out, please provide some raw data in the table Faults_IEC and Faults_GADS (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It would be helpful to find out the solution. You can refer the following link to share the required info:

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

Hi @Anonymous ,

Create a dimension table with the Category then do the calculation based on that category table should give you the correct resutl so would be something similar to:

Calculation = IF( NewDimensionTable[IEC category] = "Forced Outage*" , [GADS Calculation], [IEC Calculation])

don't know if you are doing a sum or a count or whatever calculations so I added the [..calculation] for example purposes.
