Maintaining a Format in BEx.. How?

Report requirement includes a specific order that is to be maintained.

Finished goods as well as the description is there and three key fields and the raw materials used.

The format is :

Finished Good MATNR as Central line(first raw)

Then under that the corresponding description also has to come. Under this the key figures should come.. As for each finished goods 4 key figures . But the user want to display only one time the FG number and below its description.

Then there should be a fixed format of Raw materials and that also should be in drill down format. So each key fiigure holds the value with respect to the raw materials.
