Quality Inspection in Discrete Manufacturing

Postby Noor2012 » Sun Oct 07, 2012 8:03 am

Hi,

I am working in a discrete manufacturing environment. Inspection characteristics are defined in the routing.

Example:

Manufacture of tube assembly

Operation 10: Tube Cutting > 1 quantitative inspection charactertic is defined(Check Cutting Length)
Operation 20: Bulging> 1 Qualitative inspection characteristics is defined(Check tube liquid)
Operation 30: CNC Bending> 1 Qualitative inspection characteristics is defined(Check tube bending)
.
.
Operation 90: Final Assembly> 1 Qualitative inspection characteristics is defined(check compete tube manufactured)

A Production Order of 10 quantity is entered and released, inspection lot is created. Quality Inspector checks the lot and record results via QE51n or QA32. While inspecting cutting length characteristics in operation 0010 for 10 quantity, 4 quantity appears to be rejected an rest 6 appears to be OK. As per the company rules the whole lot is valuated as rejected and production is asked to re-produce the lot.
I have the following questions:
a) Why the system doesnot stop quality inspector from recording result for Operation 0020 when Operation 10 is rejected? Am I missing any config
b) Is Quality inspector required to transact usage decision and reject the whole lot without recording rest of the operations(Op 20 till Op 90)
b) How rejection information will flow to production staff?
c) Is the prodction staff going to create the new production order and delete the old one as system will create inspection lot for new order?
d) Can any one help me providing complete business process of quality inspection in discrete manufacturing?

Br,

Because you may continue production with the four good units.

No. you can do parital confirmations at each operation level

It depends on your business.. usually a phone call from the lab to the production staff helps! If its an inprocess test usually its the operator themselves doing the testing so they already should know themselves! You canmaybe use a user exit to do an email to certain people. I think it's better thought to train the production to learn how to actually use the system and look up the info!

Not sure about what you mean here.

Hi Craig,

Thanks for the reply. It guided me to straight up my business process.

I now have the following query:

a) I am using Inspection Point functionality. Keeping the same example as decribed earlier, during result recording for quantity 10, 6 accepted and 4 rejected. After valauation, I clicked Goto> Data for Inspection Point and screen pops up to enter yield, scrap and Rework quantity. System only allows if I enter 6 quantity in yield and 4 in scrap. If I try place 4 quantity in Rework field instead of scrap, system gives an error message "Quantities cannot be specified for Sub-Operation" (Message no. RU088). Can you help me how to use re-work field in case quality asks production to re-work?

b)Another question is once confirmation is entered by quality inspector, the production staff should either re-produce(in case of scrap) or re-work if quality allows. In this situation, will the production staff be creating seperate re-work order(in case of re-work) having different order type or seperate remaining quantity(rejected quantity=4) lot order with order type PP01?

c) My third question is why system doesnot allow confirmation fields(Scrap, yield and Rework) for qualitative characteristics. How the quality person will be recording such information?

Br,
