It is possible to filter the ProductTaxationCharacteristicsCode by Sell or purchase assignment?

Hello,

I need to filter the ProductTaxationCharacteristicsCode only to retrieve codes that belongs to Sells or Purchase.

I have done some filters by using the codelist context mapping. However, i cannot identify which mapping parameter can i use for this.

Currently the ProductTaxationCharacteristicsCode retrieve both of them.

It is possible?
