I was working on couple of PowerPivot models recently and both models needed a Date Table. So here’s what I did:

1. Imported the filtered version of the Date Table (DateStream) from Azure Data Market. Added Calculated Columns to the table. Let me call this Table1

2. I copied entire Table1 and pasted it to an another PowerPivot model – let’s call that Table2

After this:

And I went to happily create data models! Later, I while testing the model (that had Table2), I realized that it had lost the “formulas” – in other words when I copy-pasted from Table1 to Table2 in PowerPivot – it did not copy-paste the formulas but it just pasted the values.

So, 1. Copy Pasting a Table in a PowerPivot does not copy-paste’s the Formula’s in the columns.

And also it does not keep the “Data connection”. In this case, Table1 was connected to Azure Data source and I could “refresh” data if I chose to. But Table2 was “Static” – In other words, It lost the data connection with the data sources. So I could not “refresh/update” data from the data source if need be.

S0, 2. If you copy Paste a Table in a PowerPivot, the newly copied table does not keep the “Data connection” to data source.
