Troubleshooting Common Pivot Table Issues

Symptom:

I keep getting the error "The PivotTable field name is not valid."

Hypothesis:

When you try to create a pivot table, you get the following error message:

The PivotTable field name is not valid. To create a PivotTable report,
you must use data that is organized as a list with labeled columns.
If you are changing the name of a PivotTable field, you must type
a new name for the field.

Result:

This message means that one or more columns in your data source do not have a header name. To correct this problem, go to the dataset you are using to create the pivot table and make sure that all columns have a header name.
