Quality Inspection in Discrete Manufacturing

[Former Member]

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,

Noor

a) When an inspection lot is released, SAP makes the inspection instruction fully.

And any characteristic in inspection instruction can be recorded even if previous characteristic has been rejected. (SAP standard)

b) Yes, the usage decision is needed for all of inspection lot, whatever results exist or not.

b) Through quality notification.. e-mail or workflow or groupware interface (will be defined by business process)

c) In SAP you cannot delete any production order which was created. Normally user performs TECO (technically complete).

Yes, SAP will generate new inspection lot for new production order.

d) Please refer help.sap.com and contact QM consultant.

Hi DoWook KIM,

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?

Br,

Noor

a) Sorry. I have no idea for rework field.

Please ask this to PP forum because it comes from order confirmation.

b) I think you have to ask rework process also to PP forum to get exact solution.

In my experience.. in most of project PP defines another order type for rework.
