Subcontracting scenario

Hi Experts,

We are having a subcontracting scenario in automobile industry -

1.The FG consists of a component 'X' say length of X is 200 mm, which in turn have raw material Y with different material code.

2. We are sending material Y to the subcontractor and receiving back material X.

3. How can we get the accountability of bi product Z at vendor end which is produced during processing at vendor as Y=X+Z?

4. Where should I maintain the parting allowance for raw material Y?

The requirement from client is the calculation of end bits(Z) at vendor end at month end, so that they can take it back from subcontractor and sell it.

Let us say you have a final product 123

X needs Y

And Z is by-product which occure during the sub-contracting of X by consuming the Y

In thiscase

123 is having routing

In Y material master MRP2 view....enter special procurement key as subcontracting( Spacial procrument key is 30),

123 has a BOM having items X and You should have a BOM for X in which Yand Z will be componenets with required quantity and Z will be with -ve quantity.

When a subcontract Po is created for X the BOM is copied to PO.

BIn Mb1b componenet Y are issued with movement type 541,

then When you make GR for that PO Y will be consumed with movement type 543. and X will take movement ype 101 and comes to stock. Then Z will be in vendor stock by movement type 545 and special stock O.

This stock you case see in MMBE with special stock O.

Also note if your not receiving back that material at the time use 551 O for sending the material to the scrap for subcontract material.

Please try and come back.
