Append in DAX
I want to create a table appending the ID and Type columns of two separate data sources. I want to include all records of each ID, not just distinct ones. I'm trying to avoid Power Query since the dataset is extremely large. I've read through forums and am not seeing anything that fits my exact situation.
That should be a JOIN operation rather than an append, either on SQL or DAX. Check this out:

Please always show your sample data in text-tabular format in addition to (or instead of) the screen captures. That allows people trying to help to readily copy the data and run a quick test, plus it increases the likelihood of your question being answered. Just use 'Copy table' in Power BI and paste it here.

Hope this helps AlB Basically, I'm looking to append like you can do in Power Query.

Hi jmhoskinson ,
I'm having a similar requirement now.
Could you share how you acheived this?Thanks in advance!
You could use a combination of UNION and SELECTCOLUMNS creating a calculated table which I did to solve a similar situation.
'calculated table name' = UNION(
SELECTCOLUMNS('Table 1',"ID", [Id],"Type",[Type],"Activity Date",[Activity Date],"Team",[Team],"Product",null),
SELECTCOLUMNS('Table 2',"ID", [Id],"Type",[Type],"Activity Date",[Activity Date],"Team",null,"Product",[Product])
)
Hope this helpsHi jmhoskinson
Try UNION(Table1, Table2). See this for details
Sorry, forgot to mention that the tables don't have the same number of columns and the tables don't have a relationship.
