Infoset - Keyfigure problem

A BEx report is generated on Infoset

having Booking ODS, Revenue ODS , Custom date Infoobject and CUstomer master InfoObject.

The problem with the report is it is having Keyfigure duplicity.

The sales order items with materials having ) key figure value are getting suppressed automatically, but in RSRT they are showing up.

I checked forums have tried the solution from blogs

"Infoset Keyfigure multiplicity Part 1"

Infoset Keyfigure multiplicity Part 1

"Infoset Keyfigure multiplicity Part 2"

Infoset Keyfigure multiplicity Part 2

"Infoset Keyfigure multiplicity Part 3"

Infoset Keyfigure multiplicity Part 3

But this did not solve the problem.

I created ZREFOBJ getting data from Revenue ODS and used exception aggregation(for Net Revenue Key Figure) with reference characteristic ZREFCHAR.

But this did not solve the problem.

Any other solution?
