I've attached SupplyLine_asPredicate, which, I hope, resolves correctly
issue of purchase system. I haven't written unit test for it - I'm still
waiting for comments on problems with invoking asPrediacte on all Supply
Lines. I'd like to know, if idea provided in this script is
ERP5-oriented and correct?

Thanks,
Luke

This is modified version of SupplyLine_asPredicate, which supports sale and purchase system.
Well - at least I (Luke) hope...
