Value 

Meaning 

frm_FullCopyAndInsert 

This is the default mode. Rows will be inserted down when filling the bands with the data from the database. 

frm_OnlyCopy, 

On this mode, rows will be copied down but not inserted when expanding bands. This means that if you have a cell at A15 and a __band__ at A10 with 4 records, after running the report Cell A15 will still be at this position. If there are more than 5 records in __band__ then the contents of cell A15 will be overwritten. 

frm_DontCopyAndDontInsert 

When in this mode, cell will just be filled, no rows will be inserted or copied. This mode can be useful when you want to do "fixed form" reports, where for example you want to have some text fixed at row 20, and don't want the report to move that row down.
