How can I change column heading across multiple tables

[cathoms]

Starting from a flat file I created a lookup/DIM table with entity names and entity_id's, merged the table with my fact tables and removed entity names column from my fact tables. So I have the following situation:

two separate fact tables with "entity_id" column (each table is for a different set of hospitals with slightly different metrics)

one "entity_lookup" table with "entity_id" column and "Entity" column

As a result, one of my filters reads "Entity"

After creating my report/dashboard and looking at it from a user perspective, it occurs to me that it would be easier for the end-user if the filter was called "Hospital" instead of "Entity". When I tried renaming columns I ran into errors because Power BI couldn't find the connections needed. How can I change all the instances of "entity" or "Entity" in column headings across my three tables/queries to "Hospital"?

Or, is there some other way to approach this?

Thanks in advance!

@cathoms you need to make this change in PQ for each table, not sure if there is a global way to make this change.

@parry2k  So just manually start renaming the columns? Does it matter what order I do this in? That is, should I do the look up table first or the fact tables or does it not matter?

Thanks!
