Thank you Evan for the quick response.
I have two tables, Table 1 connects to "Boppy2.csv". Table 2 connects to "Backhaul Input file2.csv".
I cannot recall what I have done. Suddenly Table 1 connected to "Backhaul Input file2.csv" (Please find the history screen snapshot I provided, the target file name was changed), and cannot change back to "Boppy2.csv".
Current, I only have an alternative approach: I created a new table 3 connecting to "Boppy2.csv". And I am copying all the designs (formulas, relationships, etc.) from table 1 to table 3. Then to delete table 1.
I believe there should be a better way to deal with this to save the trouble of copying design.
Thanks
