Problem while returning the subcontracting materials.

Question

Dear All,
i have received finished material A (10 pcs) from subcontractor (BOM maintained B- 200 pcs and c- 300pcs to manufacture A).
Due to quality rejection i am returning 1 pc of finished material "A" to the subcontractor. When i return through MIGO with 122 mvmt type system will display entire quantity ,ie 10 pcs, against the material document number.  Now i reduce the returned quantity of finished material as 1 pc, but subsequently BOM materials (components) are not getting reduced.
please advise how to reduce the components propotionate with finished product while returning the subcontracting items.
Eg : A received 10 pcs ( BOM- B=200& C= 300)
      returned 1 pc of A,  then system should show the components B =20 & C=30. but system shows B=200& C=300.

Answer 1

Hi,
As per your suggestions, system does not allow to do Component reversal 542 movement. How ever system will check the special stock provided to vendor 0. All the component from vendor side consumed and recived GR already for the components B and C.
The following Error message occurs while doing 542 MVMT:
Deficit of Stock w. vendor unr. 20,000 PC : B1 TEST O
Message no. M7021
Diagnosis
Shortfall below the specified stock level or quantity amounting to 20,000 PC.
System Response
If the message is an error message (E), the above is not allowed.
If the message is a warning message (W), the system will allow your input, but the warning is intended to prevent you entering a wrong quantity.
Procedure
In the case of a warning message, check the quantity entered.
In the case of an error message, change the quantity or terminate processing.
Other Possible solution,  I  have simulated
Return delivery and refer material document number
Manually change the Material A ( With 122 mvmt - qty as 1 ) With Reason for movement
And Sub component as B ( 544 O + GI receipt subc.stck ) with qty 20, similarly Sub component C ( 544 O + GI receipt subc.stck ) with qty 30) 
Finally you can check with MMBE ( Finished product A- 9 qty) MBLB - Stock provided to vendor Component B -20  and C-30 qty
I hope this with return the Finished product and consumed subcomponents respectively.
While doing Return delivery for against Material document system always with full qty and BOM qty only, We will manually change returnable qty to the vendor and Reason for the return in any business process flow.
I hope this solution resolved your issues on Return process subcontracting
Even after the Returned the goods  to the Vendor ( due to damaged - reason ) ( with 122 and 544 O+) . Later supplier finished his re -work for the returned goods / services , you can do it regular GR against PO number with as usual subcontracting receiving process ( 101 and 543 O-)

Thiru
