The procurement group class is used to group products together
when computing procurements. (tasks, physical products, ...)
The goal is that when you have one sales order of several products
and the products are pulled from the same or several location(s), to keep
having the moves grouped into pickings that represent the sales order.
Used in: sales order (to group delivery order lines like the so), pull/push
rules (to pack like the delivery order), on orderpoints (e.g. for wave picking
all the similar products together).
Grouping is made only if the source and the destination is the same.
Suppose you have 4 lines on a picking from Output where 2 lines will need
to come from Input (crossdock) and 2 lines coming from Stock -> Output As
the four will have the same group ids from the SO, the move from input will
have a stock.picking with 2 grouped lines and the move from stock will have
2 grouped lines also.
The name is usually the name of the original document (sales order) or a
sequence computed if created manually.
