there are few solutions:
1. expand opportunityproduct with 3x1:N relations: Quote/Order/Invoice
/So, I think that first solution is good enough :).
I need to select opportunity products (simply mark and/or select by
new_status), then if I make new Quote / Order / Invoice and linked particular
opportunityproducts with that instance. Do I need plugin for that?/
2. make copy of opportunityproducts into QuoteDetail, and same with Order
and Invoice. Of course with all problems with calculation etc...
/here I have not hard connection between opportunityproducts and
qoutedetails, even product description I can not copy into quote detail.../
3. make new instances for quote/order and invoice and simplify problems???
All of that is too complicated. ^^
Hm, what to do?
I just need to produce quick and fast Quote for all opportunity products
which are not involved in any documents (like Quote/Order or Invoice), and
select them on the same way Fast and easy. Same is with Order or invoice.
