One Basic difference -
Formula Columns are equivalent to Functions... They need to have a return value in their definition. whereas Placeholders can be equated to temporary Variables ? that U might declare to hold values.. and use globally in the report.
U can set the values of other placehodlers/Formula Columns in a Formula Column But U can't use a Placeholder to set the value of other place holders and formula Columns...

But can anyone please tell me what is the major difference between formula column and placeholder column. In both, we can make use of SQL code and then use that column for any of the fields in the layout. But what is the exact difference.
Can anybody help me?
