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