Suggested Answer:
Box 1: Merge -
There are two primary ways of combining queries: merging and appending.
* When you have one or more columns that you'd like to add to another query, you merge the queries.
* When you have additional rows of data that you'd like to add to an existing query, you append the query.

Box 2: Disable the query load -

Managing loading of queries -
In many situations, it makes sense to break down your data transformations in multiple queries. One popular example is merging where you merge two queries into one to essentially do a join. In this type of situations, some queries are not relevant to load into Desktop as they are intermediate steps, while they are still required for your data transformations to work correctly. For these queries, you can make sure they are not loaded in Desktop by un-checking 'Enable load' in the context menu of the query in Desktop or in the Properties screen:

Merge & Exclude the query from report refresh are correct answers. Use the merge to combine the "Products" and "Categories" queries based on the "CategoryID" column. Once we have combined the queries, we don't need the standalone "Categories" query because we have merged its data into the "Product" table. We "Exclude the query from report refresh" to ensure it doesn't unnecessarily reload when refreshing the report.

I understand the merge and the disable query concept but why don't you delete the categories table after merge

Usually the import is not a one time excercise and you will want to be able to refresh the datamodel with updated sources. Then you will need the Categories QUERY again. This first option is about deleting the Categories QUERY, not the Categories TABLE.

You should not thank him, because this answer didn't answer any question. This is a good explanation of "disable query update", but not explanation of "delete the query" in fact, the answer is simple. If i delete query, i got nothing to upload to Power BI, think about this.
