Formula to return Filter Component for posted values only

Hi,

We are currently using filter components in our AO reports such as below using the formula

=SAPSetFilterComponent("DS_1", "0MATERIAL", "ALL").

This works perfectly however this returns every material in the system and can take a couple of seconds to retrieve a list.

Is it possible for this filter component to be used to only bring back a list of the materials with posted data based on the current criteria? I.e. a list of materials in the current report the user sees.

I'm guessing i need to change the "ALL" part of the formula, but not sure what to. Can someone please help?

Thanks,

Darren
