Copy a table but not refresh the source

[nr63bi]

Hello,

Is this possible to create a table (Table 2) that copy another table which has a source  (Table 1). And then create a Table 3 that is a transformation of Table 2. 

And in Power BI Desktop, when I refresh Table 3, Table 2 is updating but not Table 1. I want refresh only Table 2. 

Basically, I just want to use Table 2 (where i do all the transformations that i want) only as a copy of Table 1 and then forget Table 1. 

Do you know how it is possible ? 

Thank you in advance

If you want to keep that first table immutable forever, turn it into a table of record values. But if you are looking for an answer to the age old question, "Can I set my source table to not refresh once the data is imported, so that the data doesn't keep refreshing from the source every time I add a new step?", then the answer is "no".
