|
|
The procurement requirement class is used to group products together
|
|
when computing procurements. (tasks, physical products, ...)
|
|
|
|
The goal is that when you have one sale 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 sale 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 procurement orders 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 (sale order) or a
|
|
sequence computed if created manually.
