Merging tables in Editor versus Lookupvalue

Hi all, I am working on different very big datasets and need to merge information from different tables.

I am doing it, right know, using the funtion "merge tables" in the Editor of Power BI Desktop.

 

The problem is that the merging of the tables at this level takes really a very very very very very long time. Definitely too much.

 

I did not even try to use hte lookupvalue formula but now I think that maybe is the optimal solution...the reason why I did not use LOOKUPVALUE it isthe following, can you please confirm if I am right or wrong?

 

- I will be obliged to load ALL the tables into the report 

- the final pbix file will have monstrous dimensions (we share it through Dropbox)

- everybody accessing the report will see all the tables and this will create confusion to the final user (or can maybe hide them somehow?)

 

What do you think about it?

 

Alessandro.

Hi @alecsonline,

 

Yeah, You are right using Merge function in editor for large dataset will mess up and it will increase file size too.
