Replace codes with full text based on table

[ReadTheIron]

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.

@ReadTheIron,

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.

Sorry, I'm having a bit of trouble understanding. I only have two tables, EventTable (which is a live connection and which I can't access in PowerQuery) and ProblemKey, which is a simple Excel import and which I can access in PowerQuery. I can create calculated columns for EventTable, but I don't know how to access it to merge.
