Question . How to create a pivot table which is dynamic (We should not be changing the data source in the addition of new rows).

There are two ways in which we could create a dynamic pivot table.
Using Data Table-Create a data table and then base your pivot table on that data table, in that case whenever a new record is added to the table, you just need to refresh the pivot table to have that new record included in the pivot table.
Using OFFSET function –Use OFFSET function to create a dynamic range for your data and give the name of the range while creating the pivot table, when a new record is added to the data, the range would automatically include that new record and since the pivot table is created on the range and not in the data, pivot table will include the new record.
OFFSET function return a range that is a specified number of rows and columns from a reference cell or range. =OFFSET(reference, rows, cols, [height], [width])
Question . How to make Pivot table automatically include new record when it is added in the data.

Answer :We can, but it won’t be making much sense as that would give us the counts of records and we would not be able to do any analytical task.
If taking the count of the values in your text filed is the purpose here, yes we can do that otherwise text columns should be placed in “Row Labels” or “Column Labels” or “Report Filter”
Question . How could we restrict pivot table from not losing its formatting after data refresh?
Answer :Go to “Pivot Table Options” and turn on the “Enable Preserve Formatting” and disable the “Auto Format” option.
Question . How can we change the data value function to MAX or MIN in a pivot table.
