On updating the Cash Flow diagram in Account Manager profile there should be an option to filter on Source Type.
This would allow to leave out certain Source Type, like Service / Sales / Purchase documents.
It would be good to have the chance to specify some kind of "default source types to be used".

When using the Cash Flow Worksheet it is possible to filter on Source Type
