Replace codes with full text based on table
I have one table of records that uses abbreviations to describe problem codes, like this:
EventTable
| Date | Problem Code |
| 1/2/2022 | ABC |
| 1/3/2022 | CDE |
| 1/3/2022 | ABC |
| 1/4/2022 | XYZ |
I have another table with a key to the problem codes:
ProblemKey
| Problem Code | Problem Description |
| ABC | Flood |
| CDE | Fire |
| EFG | Hurricane |
| XYZ | Sharknado |
I'd like to create a calculated column in EventTable that shows the full text of Problem Description
| Date | Problem Code | ProblemFull |
| 1/2/2022 | ABC | Flood |
| 1/3/2022 | CDE | Fire |
| 1/3/2022 | ABC | Flood |
| 1/4/2022 | XYZ | Sharknado |
I know I can relate the tables on ProblemCode, but I want to use the full text of Problem Description in various graphics using data from EventTable. I'm fairly sure this is a simple operation, but I'm drawing a blank. Any help appreciated!
Hi ReadTheIron ,
Here are the steps you can follow：
1. Create measure.
Measure = var _select=SELECTCOLUMNS('EventTable',"1",[Problem Code]) return MAXX( FILTER(ALL('ProblemKey'), 'ProblemKey'[Problem Code] in _select),[Problem Description])2. Result:

Hello ReadTheIron ,
First of all, go to Power Query and merge both tables with the event table and get the description columns only from both tables.
Refer to this link for instructions https://learn.microsoft.com/en-us/power-query/merge-queries-overview
then you merge these columns to show in one column and you can use it.

EventTable doesn't appear in PowerQuery; it's a live connection stored with DirectQuery.
Then merge only the other two tables and then merge the problem description columns and you can use it since there's a relation between them and event table.
