Right click the section that you're displaying the data in, presumably the Details, and select insert section below two times to create additional sections for display.
Repeat the required fields in each section.
Now you can conditionally display each section by right clicking each section and selecting Section Expert.
Place something like the following in the X 2 next to Suppress for each section:
isnull({table.field1})
or
{table.field1} = 0
section B would have:
isnull({table.field2})
or
{table.field2} = 0
Replace with the appropriate field names to check for not having a value. I assumed that this field is numeric, adjust accordingly if a string)
