When i edit the table before loading it where do actually the edit is performed?
Each edit is compiling a longer "M" code process to connect and transform your data. The edit is performed within the Power BI Desktop in the Edit Queries (Power Query).
If i am editing it in a temporary file where does the file is located (saved)?
Your datasource is never directly edited. You ingest the data into Power BI and the transformations happen within the scope of Power BI, not your originating datasource.
When i load the table on which server the table is loaded to?
Loading the data (Close & Apply) pushes the data into the Model (Vertipaq Engine) from the Edit Queries portion. The data is compressed and stored on the local machine that you are working on with the Desktop. An Analysis Services instance is actually spun up behind the scenes.
When loading a table are there any changes that are performed by Power BI to the table so it can load on the server ?
Yes, it is compressed and inserted into the Vertipaq Engine.
If it is making some changes what are they?
Compression and Optimization
Does this server have any conflicts with special characters ?
Not to my knowledge.
