Working with Rows Where the Number Cell is Blank

Blank cells are values in your report which are Null or Empty. Pentaho will hide rows and columns when all values in the row or column are blank. You can control what to show when a cell contains a blank value.

Analyzer reports are designed to break down number fields (such as "Sales") by Text Fields (such as "Product Name"). If a product did not sell, it will appear either as a zero dollars OR as a "blank" or dash ("-"). In some reporting situations the absence of a value could mean the same as a zero, but in other cases, zero might have a different meaning. The report calculations in the background behaves differently depending on whether a value is blank or a zero. For example, when the report calculates averages, zeros are taken into account whereas blanks are not.

What happens when there is no number field on the report?

The following rules apply:

• If there is only one text field (e.g. Product Line) but no number field on the report, then all values will be displayed. For example, all Product Lines will be displayed, even those that did not.
• If there is more than one text field (e.g. Product Line and Region) but no number field on the report, then the report will hide some values. You should not draw any conclusions from the report in this state. Instead, add a number field.

The rules above are designed to minimize the confusion that could appear if an expected value does not appear but weigh this against displaying every single combination of data elements.

• Grand totals for rows
