Hi,
1. Bill of Material of Lens
Suppose net weight of Lens is 20 G and runner weight is say 100 G for
multicavity mould say 5 cavities
then 1 no Lens row material in BOM will be Polycorbonet C - 20G +
(100/5) = 40 G (This is gross wt)
Runner -
(100/5)= 20 G - ( Pl. Mension Runner as -ve Sign treat as bi product-
for costing and runner generation.)

Total material required for 1 no lens (Gross) = 40 G
Runner Wt (Generates) = 20 G
You will get finished lens of net weight -= 20 G...

In Bill of materail you mension default storage location (SCRAP) for
Runner and it will be automatic backflush. Hence Runner will be
automatically Generated after production confirmat in Scrap storage
location.

2. Confirmation of Components Rejection : You confirm ok qty in
production storage location and scrap qry directly in SCRAP storage
location. U can get accountability of ok qty by selecting movement type
101 or 131 and production storage location. U can get accountabilty of
Rejected components by selecting movement type 101 or 131 and SCRAP
storage location. The runner and Rejected componets will be collected in
rejection stores which u can send to grinding / reprocessing or you can
sale.

3. Cost Estimation: At the time of cost estimate system will consider
cost as per bill of material say 40 Gram gross weight consume PCof Rs
say 10 Rs & generates runner 20 Gr of rs say 5 ( As cost of runner per
kg defined in system is less that cost of PC per kg). Then net cost of 1
Lens = 10 - 5 = 5Rs.

Costing after production confirmation of rejected components : Your
manucturing ocst and raw material consumed for rejected components are
same as OK components. You have defined two storage location 1.
Production 2. Rejected. You can check production storage location wise
and find cost accordingly.

Hi,
Instead of By Product use the runner & Scrap as Co-Product.Also do the
co product setting in Material master as well as BOM.Contact your CO
people for Co-Product mapping.
Thanks

In Injection moulding process pls.raw material is used. During this
process raw material is injected in the die through the runner.Semi
Finished components called as moulded components are produced in each
cycle.Some components get rejected during the process& runners are also
generated.Some of these rejected componenets as well as runners are
going to use again by grinding & making a new regrinded material & later
on it will be injected to manufacture moulded components again.But
sometime the scrap components & runners are sold as scrap. How to map
this scenario in system? I know I can use runner as by product & define
in BOM as ?ve qty.And how to maintain the cost related issue.

>Now on production entry of 10 nos of Lens raw material pc clear
consumed will be 1Kg.Say OK components are 5 & scrap punched as 5.And
runner is 200G.Also what will be my material type & cost for runner. __.____._
